I wonder if there is a way to check if all modules I am importing in the script are already installed and if some are not installed to install it.
For example,
import encodings
import json as json
import pandas as pd
import openpyxl
if openpyxl is the only which is missing, install it only.
I know the way with requirements.txt, but that is not an option in this specific case.
I tried with try/catch, but it is only writing the message about missing package. I am not sure how to install package from the message.
My pandas cannot read xlsx:
df = pd.read_csv(path)
with error message:
ImportError: Missing optional dependency 'xlrd'. Install xlrd >= 1.0.0 for Excel support Use pip or conda to install xlrd.
I tried to install xlrd in Commond for all those case:python3 -m pip install xlrd, pip install xlrd, pip3 install xlrd
System showed It successful to install the xlrd (I also tried to delete and install again):
Requirement already satisfied: xlrd in c:\users\<My system>\appdata\local\packages\pythonsoftwarefoundation.python.3.9_qbz5n2kfra8p0\localcache\local-packages\python39\site-packages (2.0.1)
However I still had the same error. I also tried a alternative way:
df = pd.read_excel(path, engine= 'openpyxl')
exactly same error happened for openpyxl with xlrd.
Pandas used to require xlrd but not anymore. xlrd >= 2.0 supports only xls format, not xlsx. You could downgrade xlrd to 1.2, but I prefer using openpyxl.
Also, when reading xlsx, you may need to use pd.read_excel not pd.read_csv. Here's an example of reading an xlsx file with openpyxl that works for me:
df = pd.read_excel(filename, 'Sheet1', index_col=None, na_values=[""], na_filter=False,engine='openpyxl').astype(str)
Well, I recently bought a new computer and installed Spyder as well as Python, and updated the libraries up-to-date using pip. Everything works well except for Pandas when I try to import an excel file.
This is my code
import pandas as pd
filename = "sample_sheet.xlsx"
data = pd.read_excel(filename)
And this is the error I get
ImportError: Missing optional dependency 'xlrd'. Install xlrd >= 1.0.0 for Excel support Use pip or conda to install xlrd.
I have already installed xlrd as well as openpyxl with pip, and when trying to install it again it shows the following message
Requirement already satisfied: xlrd in c:\users\lucas\appdata\local\programs\python\python39\lib\site-packages (2.0.1)
I am not the only one with this error, a friend of mine has it too. Has anyone came up with a solution? Thank you in advance for your answers.
Just copy xlrd and openpypl files (or your complete site-packages folder, if you want) from Python folder into your user appdata, to the path where python is installed.
In your case, copy all content from C:\users\lucas\appdata\local\programs\python\python39\lib\site-packages to C:\Program Files\Python39\Lib\site-packages or C:\Python39, depending on where you have installed Python
After install package:
So the problem that dependency just always install new versions of packages.
import camelot
ImportError: cannot import name 'PDFTextExtractionNotAllowed' from 'pdfminer.pdfpage' (/usr/local/lib/python3.7/site-packages/pdfminer/pdfpage.py)
If somebody has a similar problem after build project.
You should to do pip install pdfminer.six==20200517 it's install an older version.
So pdfminer was updated and package camelot stopped works.

I am trying to read a .xlsx with pandas, but get the follwing error:
data = pd.read_excel(low_memory=False, io="DataAnalysis1/temp1.xlsx").fillna(value=0)
Traceback (most recent call last):

ImportError: Install xlrd >= 0.9.0 for Excel support
I've also tried
data = pd.read_excel("DataAnalysis1/temp1.xlsx", low_memory=False).fillna(value=0)
And I Still get the same error.
Background: I'm trying to extract an excel file with multiple worksheets as a dict of data frames.I installed xlrd version 0.9.0 and the latest version(1.1.0) but I still get the same error. Thanks!
As #COLDSPEED so eloquently pointed out the error explicitly tells you to install xlrd.
pip install xlrd
And you will be good to go.
Since December 2020 xlrd no longer supports xlsx-Files as explained in the official changelog. You can use openpyxl instead:
pip install openpyxl
And in your python-file:
import pandas as pd
pd.read_excel('path/to/file.xlsx', engine='openpyxl')
Either use:
pip install xlrd
And if you are using conda, use
conda install -c anaconda xlrd
That's it. good luck.
If you are in ubuntu this work for me:
python3 -m pip install openpyxl
python3 -m pip install xlrd
This happened to me after I ran a script with cProfile a la python3 -m cProfile script.py even though xlrd was already installed and had never thrown this error before. it persisted even under python3 script.py. (Granted, I agree this wasn't what happened to OP, given the obvious import error)
However, for cases like mine, the following fixed the issue, despite being told "requirement already met" in every case.
pip install --upgrade pandas
pip install --upgrade xlrd
Pretty confounding stuff; not sure if cProfile was the cause or just a coincidence
The following should work, assuming your pip install operated on python2.
python3 -m pip install xlrd
I was getting an error
"ImportError: Install xlrd >= 1.0.0 for Excel support"
on Pycharm for below code
import pandas as pd
df2 = pd.read_excel("data.xlsx")
print(df2.head(3))
print(df2.tail(3))
Solution : pip install xlrd
It resolved error after using this.
Also no need to use "import xlrd"
This works for me:
For Python 3
pip3 install xlrd --user
For Python2
pip install xlrd --user
I don't know if this will be helpful for someone, but I had the same problem.
I wrote pip install xlrd in the anaconda prompt while in the specific environment and it said it was installed, but when I looked at the installed packages it wasn't there.
What solved the problem was "moving" (I don't know the terminology for it) into the Scripts folder of the specific environment and do the pip install xlrd there.
Hope this is useful for someone :D
Was getting the error while I was using jupyter.
ModuleNotFoundError: No module named 'xlrd'
...
ImportError: Install xlrd >= 0.9.0 for Excel support
it was resolved for me after using.
!pip install xlrd
I encountered same problem and took 2 hours to figure it out.
pip install xlrd (latest)
pip install pandas (latest)
Go to C:\Python27\Lib\site-packages and check for xlrd folder (if there are 2 of them) delete the old version
open a new terminal and use pandas to read excel. It should work.
I had the same problem and none of the above answers worked. If you go into the settings (CTRL + ALT + s) and search for project interpreter you will see all of the installed packages. Click the + button at the top right and search for xlrd, then click install package at the bottom left.
I had already done the "pip install xlrd" command from the file location of my python.exe before this, so you may need to do that as well. (you can find the file location by searching it in windows search bar and right click -> open file location, then type cmd into the file explorer address bar)
This can be because your required libraries are been installed in Python environment instead of Spyder.
https://github.com/spyder-ide/spyder/wiki/Working-with-packages-and-environments-in-Spyder
I had the same problem. Actually, the problem is that even after installing packages/libraries using pip these packages are not integrated with IDE. So, need to add libraries specifically to the ide.
First of all you need to install xlrd & pandas packages. Then try below code.
import xlrd
import pandas as pd
xl = pd.ExcelFile("fileName.xlsx")
print(xl.parse(xl.sheet_names[0]))
You need to install the "xlrd" lib
For Linux (Ubuntu and Derivates):
Installing via pip:
python -m pip install --user xlrd
Install system-wide via a Linux package manager:
*sudo apt-get install python-xlrd
Windows:
Installing via pip:
*pip install xlrd
Download the files:
https://pypi.org/project/xlrd/
Another possibility, is the machine has an older version of xlrd installed separately, and it's not in the "..:\Python27\Scripts.." folder.
In another word, there are 2 different versions of xlrd in the machine.
when you check the version below, it reads the one not in the "..:\Python27\Scripts.." folder, no matter how updated you done with pip.
print xlrd.__version__
Delete the whole redundant sub-folder, and it works. (in addition to xlrd, I had another library encountered the same)
I encountered a similar issue trying to use xlrd in jupyter notebook. I notice you are using a virtual environment and that was the key to my issue as well. I had xlrd installed in my venv, but I had not properly installed a kernel for that virtual environment in my notebook.
To get it to work, I created my virtual environment and activated it.
Then... pip install ipykernel
And then... ipython kernel install --user --name=myproject
Finally, start jupyter notebooks and when you create a new notebook, select the name you created (in this example, 'myproject')
Hope that helps.
Please make sure your python or python3 can see xlrd installation. I had a situation where python3.5 and python3.7 were installed in two different locations. While xlrd was installed with python3.5, I was using python3 (from python3.7 dir) to run my script and got the same error reported above. When I used the correct python (viz. python3.5 dir) to run my script, I was able to read the excel spread sheet without a problem.
As #WojciechJakubas mentioned to install openpyxl instead of xlrd, I used openpyxl and it worked.
pip install openpyxl
import openpyxl
path = "path to file.xlxs"
wb_obj = openpyxl.load_workbook(path)
sheet_obj = wb_obj.active
length_col = sheet_obj.max_row
print("Length of rows : ", length_col)
I hope it will help lot of people in 2023.
