I downloaded the nltk package from https://github.com/nltk/nltk_data (I cannot use nltk.download() due to proxy issues) and put it at C:\nltk_data. When I try 'import nltk' from the python interpreter I get this error message:
Traceback (most recent call last):
File "", line 1, in
ImportError: No module named nltk
I do not know how to get the python interpreter to see the folder. Any help would be greatly appreciated.
Thanks!
In my opinion, the Python interpreter will check the library path before its running.
You can use sys.path in python interpreter to check the place.
Always by default, python will add the running path to the library path which in linux like "./".
If you want to run the python in another path, In Windows there are two ways to solve this problem.
You can add a environment variable
C:\Users\Administrator>set PYTHONPATH=C:\nltk_data
Or you can add it in you python script like:
sys.path.append("C:\nltk_data")
PS:
Dobule check the path(\ or /) which is in different types between Windows and Linux.

I am working on a Python project in Pycharm (2020.1.2) on Windows 10.
For this project, I cannot use the standard Python interpreter, I have to use my own located at C:\some\path\here\python\27_64\python.exe (Python 2.7.3).
Backstory may be important:
I have added this path to the system path for both myself and all users, and placed it ahead of %LOCALAPPDATA%\Microsoft\WindowsApps to try to prevent the Microsoft store from popping up whenever I try to run python on the command line - however I don't feel like this change to the path variable has made a difference, as the Microsoft store still pops up.
I can start a Python shell by running C:\some\path\here\python\27_64\python.exe, so I know it technically works. When I do so; the sys.path is as follows:
['', 'C:\\another_place\\Python_2.7.3_x64\\python27.zip',
'C:\\some\\path\\here\\python\\27_64\\DLLs',
'C:\\some\\path\\here\\python\\27_64\\lib',
'C:\\some\\path\\here\\python\\27_64\\lib\\plat-win',
'C:\\some\\path\\here\\python\\27_64\\lib\\lib-tk',
'C:\\some\\path\\here\\python\\27_64',
'C:\\some\\path\\here\\python\\27_64\\lib\\site-packages']
Anyway, when I try to run a Python console (not even my script), this is the message I get in Pycharm:
C:\some\path\here\python\27_64\python.exe "C:\Program Files\JetBrains\PyCharm 2020.1.1\plugins\python\helpers\pydev\pydevconsole.py" --mode=client --port=59771
Traceback (most recent call last):

import _socket
ImportError: DLL load failed: The specified procedure could not be found.
Process finished with exit code 1
I have gone to Settings>Project:[name]>Project Interpreter and set it to C:\some\path\here\python\27_64\python.exe (and rebooted Pycharm to be sure). That said; in the settings window no packages are shown and it claims that Python packaging tools can not be found.
When I click the link to install them (circled in red), they can not be installed due to this error:
ImportError: cannot import name _remove_dead_weakref
Are there other variables or settings I need to change?
Thanks
EDIT
Uninstalling the first Python on my Path (C:\\another_place\\Python_2.7.3_x64\\python27.zip) just makes everything so much worse
EDIT 2
I added the PATH variable manually to both the Python console settings and to the Run/Debug settings in PyCharm (and restarted the program), the result is still the same
I had a similar issue. This procedure fixed my issue.
Try the following:
run print(os.environ['PATH']) in the system terminal using the same interpreter
copy the result and add as PATH environment variable to your Run/Debug Configuration
do the same for Python Console settings
I hope it will work.
It seems that the interpreter is not being recognized by the windows as a result of which you are unable to install packages.
Also, I suppose the interpreter should be present in the bin folder of your python folder. The interpreter does not have a .exe extension.
I would suggest installing anaconda python 2.7 64 Bit windows package installer and using the condo environment and work on python 2.7
Here is a link I found for Python 2.7 on Windows hope this helps:
https://docs.python.org/2/faq/windows.html
Had the similar issue, in my case it was always trying to find libraries in PostgreSQL installation directory.
Mentioning sys.path helped me here! I tried printing it from inside my script and realized that PostgreSQL directories appear earlier in the list than Python directories.
SO, how I finally fixed it -- added PYTHONPATH environment variable to my Run configuration in PyCharm like this (replace with paths to your Python installation directory):
PYTHONPATH=D:\PROGRAMS\Python\Python3.9\DLLs\;D:\PROGRAMS\Python\Python3.9\lib\;D:\PROGRAMS\Python\Python3.9\;D:\PROGRAMS\Python\Python3.9\lib\site-packages
This helps to put desired directories at the beginning of the list, thus they are searched first and required libraries are found as it is supposed to work.
All of my project files in VS code suddenly gives an error saying that it cannot import modules (even tho the modules are local i.e same directory and they used to work pretty well before).
The code works fine in pycharm but not in VS code, any idea whats going on?
Code:
from backend.util.crypto_hash import crypto_hash
from backend.config import MINE_RATE
error:
env DEBUGPY_LAUNCHER_PORT=34625 /home/nikhil/python-blockchain/blockchain-env/bin/python /home/nikhil/.vscode/extensions/ms-python.python-2020.3.71659/pythonFiles/lib/python/debugpy/no_wheels/debugpy/launcher /home/nikhil/python-blockchain/backend/app/__init__.py
Traceback (most recent call last):
File "/home/nikhil/python-blockchain/backend/app/__init__.py", line 2, in <module>

Close VS Code,
start it again, Go to File > open folder (open your project folder in vs code),
if it gives a prompt to select a existing virtual environment, select that.
Then you should be good to go.
More unrelated information:
I assume the issue here is that there's some problem with VS Code not recognizing the virtual environment properly. This has happened to me several times and I cannot point out why that happens. But the above solution is a quick fix and always works for me.
I'm not sure if this will resolve OP's (ten-month old) question, but I've been struggling with the same error using debugpy while trying to configure VSCode's debugger.
Step 4 of this resource resolved the issue for me. In particular, I was using the -m flag when running debugpy, but the module to be run was not in the current working directory. Once I had changed this, the debugger worked as expected. As an example, if the command was originally:
python -m debugpy --listen 0.0.0.0:5678 ./some/directory/my_script.py
then the following two commands would rectify it:
cd ./some/directory
python -m debugpy --listen 0.0.0.0:5678 ./my_script.py
After doing this, I no longer received the "No module found" error.
The main reason is that VSCode does not automatically configure environment variables for you, but PyCharm does. The simplest method is adding your module file to system path.
import sys
sys.path.append(module_file_path)
The better solution is to config your environmental path named PYTHONPATH, adding related module path to it, and after that you will no longer need import system path manually.
Hope it works!
I created a project in Pycharm including a gp.py, copied the project folder to another machine and tried to run the gp.py script from command line using python gp.py. However I got a error
Traceback (most recent call last):
File "gp.py", line 2, in <module>
from gplearn.genetic import SymbolicRegressor
ModuleNotFoundError: No module named 'gplearn'
The thing is I could see this gplearn library I used in the project folder, like below. The screen shot is not from Pycharm but the folder I copied to another computer. I tried to place the gp.pyinside and outside venv folder but neither worked. Could you please help to point out what the problem is ? Many thanks
gplearn package is not installed in the new machine.
Go to cmd prompt/terminal in pycharm and execute below line:
pip install gplearn
Sound like you are seeking for a method to deploy your script to end user, in this case maybe you can give Pyinstaller a try.
I'm writing a simple test for Android app and it fails while trying to connect my device with this log:
Traceback (most recent call last): File "D:/MonkeyRunnerTest/test/LaunchTest.py", line 3, in <module>
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice ImportError: No module named 'com'
I use Pycharm 2.7.3, Python 3.3.2, juthon-standalone-2.5.3. I've tried to launch my test project on Eclipse with PyDev and Intellij Idea with Python plug-in, but with the same result. Also I've added environment variable PYTHONPATH containing the path to monkeyrunner and jython source to my operation system (Windows 7), it didn't help.
Any suggestions for this issue?
You should only use monkeyrunner interpreter to run monkeyrunner scripts. Forget about python, jython, etc.
From you command line try:
monkeyrunner LaunchTest.py
and it will work.
You can find some instructions to use monkeyrunner with Eclipse+Pydev. See the updates at the bottom of the page.
Assuming you have the proper modules installed: They aren't in your system path. You can check your system path manually to see if the directory is there by doing
import sys
print sys.path
You can append to sys.path as you would any list, but it's probably better to modify it via your OS, rather than on the fly appending. (which is temporary, sys.path reverts to its original state after the end of the script in python)
I'm trying to use Gnuplot in a Python script I'm writing in Sublime Text. Whenever I build, I get the error message
Traceback (most recent call last):
File "..." line 4, in <module>
import Gnuplot
ImportError: No module named Gnuplot
If I do the exact same code lines directly in Terminal, I have no problem importing and using Gnuplot.
The import error seems to be common, just with other modules. Usually the fix is related to PYTHONPATH. However, Gnuplot is on my computer located in
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
and should thus be found.
Anybody who's got a fix to this one?
Sublime Text 2 comes with its own Python interpreter which sets PYTHONPATH independently from the system Python interpreter you are referring to.
Please see this question how to set a different PYTHONPATH for Sublime. Please note that if the library you are using was compiled against a different Python version than Sublime is using loading the native dynamically linked libraries will probably cause Sublime Text 2 to crash.
