New to anaconda and spyder. using different sys.executables - python

For some reason when I install a package through Anaconda, it is not available in Spyder. When I execute the following command in anaconda and in spyder I get different files.
Anaconda:
import sys; sys.executable
'C:\\Users\\onp1ldy\\AppData\\Local\\conda\\conda\\envs\\deeplearning\\python.exe'
Spyder:
import sys; sys.executable
'C:\\Users\\onp1ldy\\AppData\\Local\\conda\\conda\\envs\\deeplearning\\pythonw.exe'
Can anyone help me with this? I am not sure what to do...

By Default: You can control which one of the executables will run your script. Such as, when opened from Explorer by choosing the right file_name like:
1. python.exe is a terminal-based (console) application to run and lunch CLI-Type Python-scripts.
*.py files are by default associated (invoked) with python.exe
2. pythonw.exe is a GUI-based app for lunching Graphical User interface-(No_UI_at_all_Scripts)
*.pyw files are by default associated (invoked) with pythonw.exe
TO SUMMARIZE AND COMPLEMENT MY OPINION:
First of all, Python-Binary that you're trying to run doesn't have Package installed. It does have a directory path named as package_name like torch at the search path of modules, and it is being treated as a Package namespace like for me:
torch.Tensor(5, 3)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'torch' has no attribute 'Tensor'
For your current python binary, you need to install your package correctly. Visit Reference: Home-Page
python3.7 -m pip install http://download.pytorch.org/whl/cu80/torch-0.2.0.post3-cp35-cp35m-manylinux1_x86_64.whl
python3.7 -m pip install torchvision
More importantly, replace the pip or pip3 as the Home-Page instructions use with python3.7 -m pip;. In the end, don't forget to include python3.7 to be the full path to your Python binary.

Run this in spyder and see if you can access the package.
import subprocess
subprocess.call('pip install numpy', shell=True)
import numpy

based on your description the problem may be connected to the Python interpreter that you are using in Spyder. There is a similar issue on Stack Overflow at this url:

You can try the solution proposed by Bremsstrahlung.
Hope this can help you.

ModuleNotFoundError: No module named 'tensorflow' Vs code

I am running on windows 10. I am having problems with importing TensorFlow. I am in Vs code. I installed tensorflow using pip3. And here is the error:
Traceback (most recent call last):
File "c:/Users/USER/PycharmProjects/tt/main.py", line 1, in <module>
import tensorflow as tf
ModuleNotFoundError: No module named 'tensorflow'
I created my project in pycharm.
I am using python 3.7.5 and TensorFlow 2.0.0. This is how I installed TF:
pip3 install tensorflow==2.0.0
please help I was having this problem for a week.
Thanks , In Advance
For your work/project, please try to create a new virtual environment and then install all your required packages.
Like this:
$ python3 -m venv env
Activate it:
$ source env/bin/activate
and then install the tensorflow package inside your virtual environment:
pip3 install tensorflow
I think you need to create environment separate
and then install tensorflow..
for more information regarding envirnoment Link
Do you have several different python environments on your pc? Which python interpreter are you using when you install tensorflow?
The Status Bar will show you the current interpreter in the lower left corner. Check whether it is the same with the one you use when you install tensorflow.
enter image description here
I was getting your exact error, but this worked for me:
File->settings
Workspace tab
Search for "interpreter"
Put the complete path to the python.exe you want to execute under "default interpreter path"
It seems VSCode either found (or included) an older version of python that couldn't find the things I installed with pip.
I am a bit of a python newb and I'm guessing the venv approach is superior, but I couldn't get that cooperating with VSCode on windows.

ModuleNotFound error but module has just been installed

I'm using Windows 10, Python 3.6.4. I'm trying to use the module Pyperclip and have installed it with pip:
c:\Users\Bertie>pip install pyperclip
Requirement already satisfired: pyperclip in c:\python36\lib\site-packages (1.8.0)
But when I try to run a program which uses this module, I get this error:
c:\Users\Bertie\scraping.py test
Traceback (most recent call last):
File "C:\Users\Bertie\scraping.py", line 3, in <module>
import webbrowser, sys, pyperclip
ModuleNotFoundError: No module named 'pyperclip'
How can I fix this? Thank you.
The reinstall trace shows you install the packge successflly for python36.
Check if there is more than one python in your system. Type "python" in your windows cmd console, and check the python version to see if python36 is the default one. Then explicitly use the python interpreter to start the script "python your_python_script.py".
Where is the py file? Maybe try cd-ing into the folder and run python (python3) scraping.py?
Also check that you have installed the correct interpreter and are using the correct version of python.
Maybe You Installed pyperclip in conda env or a virtualenv and you forgot to activate it ?
Because This Has Happened To Me Many Times.
Or Maybe You Have 2 Instances Of Python installed on your computer and you accidentally installed pyperclip in the other instance of python ?

Why doesn't module import while it actually exists?

My project structure looks like the following:
my-project:
dialog
utils
path.py
After install by 'pip install .', in PyCharm, I can import successfully either of the two:
from dialog.utils import path
import dialog.utils
Then I can refer to it as below:
path.module_path() // OR
dialog.utils.module_path()
It doesn't run into any problem. I can also do this in iPython's terminal. However, when I run a python through terminal:
python3 run_dialog
run_dialog.py import 'path' as shown above, it always reports this problem:
Traceback (most recent call last):
File "run_dialog.py", line 15, in <module>
import dialog.utils
ModuleNotFoundError: No module named 'dialog.utils'
So basically, I can run this code in both PyCharm and iPython terminal, but not in the project with 'python3 run_dialog'.
Why is that?
Try this
import sys
sys.path.append('my/path/to/myModule/dir')
import myModule
The Python interpreter needs to know to path to your imported module.
However, a better approach would be setting PYTHONPATH to your project directory like this
set PYTHONPATH=my/path/to/project
In my humble opinion, the Pythonic solution would be to install your package in the activated virtual environment using an "editable" install.
“Editable” installs are fundamentally “setuptools develop mode” installs.
use the pip install -e <path> option to do an editable install
(venv) $ pip install -e path/to/myproject # wherever myproject/setup.py is located
you can use pip list to confirm your package is installed into the virtualenv as an editable package, ie the path to the package is listed
$ pip list
myproject 0.1 path/to/myproject
pip 19.1.1
setuptools 41.0.1
changes saved to your package take effect each time you restart the interpreter and reload/import the package, letting you "edit" or "develop" your package

python cannot find module that is installed on windows

I have installed the requests module
C:\Python34\Scripts\easy_install.exe requests
i got to the folder location
C:\Python34\Lib\site-packages\requests-2.13.0-py3.4.egg\requests
I have a path variable in system
C:\Python34\Lib\site-packages
yet when i run my script
C:\Users\beast\Desktop>update.py
I get the error No module named 'requests'
Traceback (most recent call last):
File "C:\Users\beast\Desktop\plex_playlist_update.py", line 17, in <module>
import requests
ModuleNotFoundError: No module named 'requests'
I tried installing using pip just in case
python -m pip install requests
Requirement already satisfied: requests in c:\python34\lib\site-packages\requests-2.13.0-py3.4.egg
I am new to python and I cant find an answer anywhere.
UPDATE:
I found a command to check my python search location.
C:\Users\beast\Desktop>python -c "import site; print(site.getsitepackages())"
['C:\\Python34', 'C:\\Python34\\lib\\site-packages']
I think it has to do with C:\Python34 vs C:\python34? How do i check or fix this?
The problem here is maybe because of the different versions of python installed.
If you are a Windows user, you can go to Path in Environment variables and remove the paths to unnecessary versions of python (if any). Modules installed for one version of python won't work in another version.
So I ended up going with python environment. Per python documentation it is the way to go anyway. The below command are run on the root folder of the python app.
py -m venv env
then
./env/Scripts/activate
I then ran my pip upgrade and everything is working. Obviously this did not fix it computer wide. just for my python app. But from documentation this is better because of version control of the whole enviroment.
This creates a "env" folder at the root which will have all the packages installed. Need to install all requirements again or use the requirements.txt file.

vlc import error in python script + ubuntu 14.04LTS

I want to import the vlc from my python script, but it is getting error like follows:
Traceback (most recent call last):
File "test.py", line 3, in
import vlc
ImportError: No module named vlc
How to solve this problem??
For people stumbling upon this answer in 2020 and using Debian Linux, try the following command:
sudo pip3 install python-vlc
looks like your files are not on "sys.path", from where usually python tries to pick up imports
Try and access from interpreter. just type "import vlc" and see if that works.
If it does't work then just copy your vlc module files (I guess its vlc.py) to your python sys.path location and try again
go through these links, it may help
https://docs.python.org/2/using/cmdline.html#environment-variables
https://docs.python.org/2/library/sys.html#sys.path
Try to use pip install python-vlc in command prompt (if you are using windows). This will remove that error, as vlc is not yet installed on your system.
If you are using Ubuntu or other Linux Kernel OS, then first install pip (and python) on your system using whatever your package manager is (if necessary), then do pip install python-vlc.
