I was following this guide https://realpython.com/blog/python/setting-up-a-simple-ocr-server/ and got to the part where I run cli.py python flask_server/cli.py but I get
python cli.py
Traceback (most recent call last):
File "cli.py", line 3, in <module>
import pytesseract
ImportError: No module named pytesseract
How can I solve this ?
I also saw that I have multiple versions of python. I have linux-kali installed with the latest updates.
Something else: he runs the command like python flask_server/cli.py- where is that flask_server located ? I simply ran it like python cli.py(I was in some directory in which I created the file).
Python import errors usually boils down to one of those three cases (whether is is modules you developed; or modules distributed as packages):
You did no install the required package. Googling pytesseracttells me its an OCR that is distributed and installable using Python package manager tool pip by running pip install pytesseract in your favorite shell.
You did install the package, but is is not in your python path.
(Less often) You did install the package, and it is in your python path, but you used a name already in user by Python, and the two are conflicting.
In your case, I strongly think this is the first one. Case 2. and 3. can be assessed by calling python -v your_script.pyas described in this answer.
I had a similar error. So I hope to help people with this kind of problems.
In my case,
I tried to run python code using pytesseract lib on Raspberry pi 3.
$ pip install pillow
$ pip install pytesseract
(followed by https://www.pyimagesearch.com/2017/07/10/using-tesseract-ocr-python/)
and then, I made an example.py to test.
example.py
try:
import Image
except ImportError:
from PIL import Image
from pytesseract import *
print(pytesseract.image_to_string(Image.open('YOUR_IMAGE_PATH')))
and then, when I run this code, I got below error like you.
ImportError: No module named pytesseract
After I saw the #Bertrand Caron's answer, I found a solution.
My problem was package library path.
I also have multiple versions of python, 2.7 and 3.5, like a writer.
When I run command $python --version on linux, the result is Python 2.7.13.
In my case, when I installed a pytesseract package,
it was stored in "/usr/local/lib/python3.5/dist-packages/pytesseract".
And When I ran $python -v example.py, I found the referenced packages path hadn't been same with upper pytesseract package directory.
cf.
installed pytesseract path : /usr/local/lib/python3.5/dist-packages/pytesseract
actual referenced lib path, when running : /usr/lib/python2.7/dist-packages/
So, I copied pytesseract, located in "/usr/local/lib/python3.5/dist-packages/pytesseract" to "/usr/lib/python2.7/dist-packages/"
Then, Solved!
In my case, I was running it in Jupyter so I used this command,
! pip install --user pytesseract
But I forgot to restart the kernal. You need to restart the kernal after installing the pakcage
I had the same error. My solution is
$ pip3 install pytesseract
since I have python 2 and python 3 installed together.

I'm having a problem with PIL where vs code says there is no module named PIL when there is. If I run the file without vs code the module imports fine. In the vs code problem tab it says this:
import PIL could not be resolved from source. Pylance(reportmissingmodulesource)
I know the library is installed because if I do pip install pillow, it says requirement already satisfied.
Things I've tried to fix it: reinstalling python, uninstalling and reinstalling pillow, upgrading pip, installing the PIL library(pip install Pillow-PIL).
None of these things worked so I am out of ideas for things to try. Could someone help me with this?
This part is important:
If I run the file without vs code the module imports fine
If something like this happens, then you are not running the same python interpreter, because modules are always installed to specific installations of python that you have.
Do the following:
Add to your script the first two lines
import sys
print(sys.executable)
This will print the path to the python executable that is interpreting that script. If you now run this script with and without vs code, it should print two different python paths. Now you can install to the python interpreter that is being used by vs code specifically by typing
/path/to/python/used/by/vs/code/python -m pip install pillow
in case someone stil has this problem on Mac or it didn't work, I used the code "python3 -m pip install pillow" in my vs code in terminal below but I had different code "from PIL import ImageTk,Image"
If anyone stumbles upon this problem and can't figure out what's wrong:
the first thing to do is simply restarting the Visual Studio Code instance.
That worked for me after running pip3 install Pillow from the VSCode terminal.
How about this?
pip install Pillow
For reference: https://pypi.org/project/Pillow/
I'm using a Kubernetes inventory builder script found here: https://github.com/kubernetes-sigs/kubespray/blob/master/contrib/inventory_builder/inventory.py
On line 36, the ruamel YML library is imported using the code from ruamel.yaml import YAML. This library can be found here: https://pypi.org/project/ruamel.yaml/
On my OSX device (Mojave 10.14.3), if I run pip list, I can clearly see the most up to date version of ruamel.yaml:
If I run pip show ruamel.yaml, I get the following output:
I'm running the script with this command: CONFIG_FILE=inventory/mycluster/hosts.ini python3 contrib/inventory_builder/inventory.py 10.0.0.1 10.0.0.2 10.0.0.4 10.0.0.5
Bizarrely, it returns the following error:
Traceback (most recent call last):
File "contrib/inventory_builder/inventory.py", line 36, in <module>
from ruamel.yaml import YAML
ModuleNotFoundError: No module named 'ruamel'
I have very little experience with Python, so don't understand how this could be failing. Have I installed the library incorrectly or something? From the documentation on the ruamel.yml project page, it looks like the script is calling the library as it should be.
Thanks in advance
In my case, I was installing this with pip3 install ruamel.yaml, and it was puting the package in /usr/local/lib/python3.9/site-packages/, but the python3 binary on the machine was pinned to Python 3.7, so trying to import that module was sending the ModuleNotFoundError message.
What helped to fix this, was to install the module with python3 -m pip install ruamel.yaml, running pip via the python3 binary makes sure it runs on the same version, in this case 3.7, and gets installed via the correct version number site-packages.
pip is set to point to the Python 2 installation. To install the library under Python 3, do pip3 install ruamel.yml.
you're using python 3 and want to use the package that is with python 2. Go to the directory where your python 3 is, navigate to Scripts and use the pip in there to install the needed library.
This helped me (adding version number to python):
CONFIG_FILE=inventory/mycluster/hosts.yaml python3.6 contrib/inventory_builder/inventory.py ${IPS[#]}
[python 3.10.x].
There is no package called ruamel.yaml
what worked is pip install ruamel-yaml
I need to use netcdf but do not have install permission for python modules. I have downloaded netcdf-0.1.2.tar.gz from here: https://pypi.python.org/simple/netcdf/ and unzipped the tar ball. I have been following this stack overflow post in an attempt to use the module but have had no luck so far:
(Python) Use a library locally instead of installing it
here is what I have tried:
Installing virtualenv:
I do not have permission to do this
python setup.py install -- user:
again, I don't have permission
running my script with netcdf as my current working directory:
I tried this as well, here are the issues I have run into:
first I went into netcdf-0.1.2 and made a new file called asdf.py
which contains the following:
import netcdf
print("testing")
running python asdf.py gives the following error:
Traceback (most recent call last):
File "asdf.py", line 1, in <module>
import netcdf
File "/.../Downloads/netcdf-0.1.2/netcdf/__init__.py", line 1, in <module>
from netcdf import *
File "/.../Downloads/netcdf-0.1.2/netcdf/netcdf.py", line 1, in <module>
from netCDF4 import Dataset, numpy
ImportError: No module named netCDF4
I'm not sure how to fix this error, any help would be greatly appreciated
in case this is somehow relevant, the version of Linux I am using is 3.2.0-23-generic
also I have numpy installed already
Easest would be to install Anaconda or Miniconda with your user rights.
Anaconda already as netCDF4installed. In case of Miniconda install with:
conda install netcdf4
If you have Python 3 installed, then you will have the venv package in the standard library, so you do not need "virtualenv" to be installed for you separately (as would be the case with Python 2). Instead use python3 -mvenv , in a similar way to how you would use virtualenv, for example:
python3 -mvenv /path/to/my_venv
or to include any non-standard packages already installed on the system:
python3 -mvenv --system-site-packages /path/to/my_venv
After that, you should be able to activate the environment and pip install packages, e.g.
source /path/to/my_venv/bin/activate # for csh use activate.csh instead
pip install netCDF4
Remember to source the activate script at run time as well as installation time:
source /path/to/my_venv/bin/activate
python
and you should then find that in your python session you have the netCDF4 package available, e.g.
import netCDF4
my_dataset = netCDF4.Dataset('myfile.nc')
Of course, substitute the actual path in place of /path/to/my_venv above.
None of this requires any root privileges.
(And as someone else has suggested, another option for you is to use conda.)
I'd also like to highlight that the package is imported using capitals
import netCDF4 as nc
This might not matter on a mac, but for Windows it is key.
I am running Windows 7 and using Python 2.7.
I have installed openpyxl using easy_install. It looks like the installation was successful. I changed the directory and fired up Python.
>>> import openpyxl
>>>
So, this should mean that Python is able to find openpyxl. However, when I execute a simple test program excell_tutorial1.py and run it, I get the following:
Traceback (most recent call last):
File "C:/Python27/playground/excell_tutorial1.py", line 7, in <module>
from openpyxl import Workbook
ImportError: No module named openpyxl
Very confusing! It could find it in prompt line but not in the program!
import os, sys
the_module ="C:\\Python27\\Lib\\site-packages\\openpyxl-2.3.3-py2.7.egg\\openpyxl"
if the_module not in sys.path:
sys.path.append(the_module)
if the_module in sys.path:
print sys.path.index(the_module)
print sys.path[18]
so, this gives me:
18
C:\Python27\Lib\site-packages\openpyxl-2.3.3-py2.7.egg\openpyxl
Anyone can think of what the problem might be?
Much appreciated
I had the same problem solved using instead of pip or easy install one of the following commands :
sudo apt-get install python-openpyxl
sudo apt-get install python3-openpyxl
The sudo command also works better for other packages.
While not quite what you ran into here (since you state that you are using python 2.7), for those who run into this issue and are using python 3, you may be unintentionally installing to python 2 instead. To force the install to python 3 (instead of 2) use pip3 instead.
See this thread for more info:
No module named 'openpyxl' - Python 3.4 - Ubuntu
Try deleting all openpyxl material from C:\Python27\Lib\site-packages\
Once you do that try reinstalling it using pip. (This what worked for me)
At times this can be a simple permission issue. As it was in my case. I installed it in my local directory with my login.
python ./setup.py install
but some of the other user were not able to import the module.
They were getting this error:
ImportError: No module named openpyxl
Hence I simply gave exe permission to 'others'
chmod -R 755
That solves the problem at least in my case.
Go to the directory where pip is installed, for eg.C:\Python27\Scripts and open cmd (simply type cmd in address bar ). Now run the command "pip install openpyxl". It will install the package itself. Hope this will solve your problem.
Try this:
!pip install openpyxl
I had the same issue on 3.8.2
I found out that python was installed in two locations on my machine (probably py and python, just a guess)
Here:
C:\Users<userAccount>\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8\LocalCache\local-packages\Python38
and Here:
C:\Python38
I deleted the one in my C drive and everything is working well now. I would double check to see where your packages are getting installed first, before deleting. Which ever one is being used, keep that one.
For this case, check to see where this package got installed:
C:\Users\<userAccount>\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8\LocalCache\local-packages\Python38\site-packages\openpyxl
keep that directory.
What worked for me was to open the terminal as an administrator, cd to the 'scripts' file of where python (different for each version) is stored, and then install using pip:
cd C:\Users\Salfa\AppData\Local\Programs\Python\Python39\Scripts
pip install openpyxl
This resolved the problem for me.
Please only respond to this post if you use Python on Windows, rather than Mac or Linux.
Error message:

Questions:
Regarding windows 7, python 3.4.3 and numpy-1.9.2, are there any
conflicts that would prevent these from working together?
Into which directory (please write out the complete directory path
starting with "C:") should I extract the contents of the numpy zip
file?
What is the exact command that I need to type into python command
prompt in order to install numpy?
Thanks in advance for your assistance
I was also facing this issue where in I tried using
import numpy
But it has given me error "ImportError: No module named 'numpy'"
I installed numpy using "C:\user>python -mpip install numpy" and it was successfully installed.
However I was again getting the same error
Then I checked that the path where in numpy was intalled was not listed in
import sys
print(sys.path)
Then I appended my path wherein numpy was installed using ">>> sys.path.append(r"C:\Users\xxxx\AppData\Roaming\Python\Python38\site-packages").
The above command worked fine, still problem not resolved then I restarted my python session again.
Finally it worked..!!!!(As after every append we have to restart our python session).
1) No there isn't.
2) You can use pip. pip install numpy
If you don't have pip installed, install it, its the most often used way of installing python packages. Yes it is possible to do under windows.
3) Once you have the python command prompt, you already have python installed.
1) no
2) It doesn't actually matter as pip or the installer will figure that out for you. However, just so you know, pip or whatever will install numpy into your site-packages folder.
3) I recommend downloading the NumPy installer from SourceForge:
http://sourceforge.net/projects/numpy/files/NumPy/1.9.2/
Then you don't have to worry about having the right compiler installed. However, if you want to use pip, then you'll need to install the appropriate compiler. This is documented at the following locations:
Microsoft Visual C++ Compiler for Python 3.4
https://matthew-brett.github.io/pydagogue/python_msvc.html
I'm not even close to an expert on Python. That said, I like the notion of "keep it simple." I chose to install a Python distribution that already includes numpy. Specifially I installed Python(x,y). Everything seems to be working just fine right after install. I appreciate all those who commented on my question. Thanks
