I'm trying to read text from a PDF, but every library I use says that the import cannot be resolved. I'm running Windows 11 and using WSL with Ubuntu 20.04 in VSCode, I've installed tabula-py and pdfminer, but I get the same error with both.
I've also changed the Windows env paths to reflect my java installations, but I know that WSL seems to be a completely separate entity from Windows
Import "tabula" could not be resolved
Import "pdfminer.high_level" could not be resolved
What am I missing?

I've been trying to use the packages pandas, numpy, matplotlib, seaborn in my "Visual Studio Code", but the program keeps showing me the following message:
"import pandas could not be resolved from source Pylance(reportMissingModuleSource)"
Previously to Visual Studio Code I installed "Anaconda" to use Jupyter, and now it says that i have the existing packages (pandas, numpy...) but keeps appearing this message that doesn't allow me to use pandas in my Visual Studio.
Anyone could help me to solve this issue?
I tried installing again all the packages to check if they didn't exist but apparently are installed all of them but in another route. I can't find how is the way to put them so the Visual Studio Code recognizes them and I can use them.
I also received similar an error on my IDE VSCode and currently using mac m1 .First we need to make sure that the python3 interpreter version from terminal version is the same with our python version selection in VSCode.
open terminal.
type 'python3'
then you will see your python version.(my python3 version is 3.9.12)
python3 version
open your IDE VSCode
open any/current folder that related to python project on IDE VSCode
Check your python version at the bottom right on IDE VSCode (in my case the python version is 3.10.64)
change or switch VSCode python version from 3.10.64 to 3.9.12 (same with your python version on your pc)
done
I also had this problem and it was because of version mismatches.
I had installed Python AND Anaconda. If anyone else has done this and gets this error, you need to uninstall both. Then install Anaconda only; Python (the compatible version) is installed as part of that process.
See https://docs.anaconda.com/anaconda/install/windows/
Also, you can click on the interpreter version at the bottom left corner of the screen (Vs.code 2022) it should show a dropdown menu with a list of the available and selected python interpreter. Click on add interpreter path and paste the path to the python interpreter with all the required modules installed and click enter. This should resolve the problem.
I re-entered the path to Python interpreter and warning disappeared. Hope that helps you.
Another way I solved this issue having followed every other installation process to the letter was deactivating Pylance. Works a (py)charm now.
I encountered this problem in VSCode under remote to WSL2 of Windows 10. The Python version is correct as interpreter (3.9.13) and the terminal in VSCode is also under the same envs (ie. VSCode ran "conda activate xx" and (xx) is shown in prompt)
Originally, I tried to install the pandas by the following command.
sudo apt-get install python3-pandas
Pandas was installed successfully as stated in the terminal but the problem is still there.
When I try to install pandas by the following command, the problem solved.
pip install pandas
I am using miniconda. Spyder is installed in the base environment and configured with spyder_kernels to point to the interpreter in my work environment called py37. That is where numpy, pandas and matplotlib are installed.
When I activate py37 in a command prompt and use python there I can use matplotlib in my scripts without incident.
When I attempt to run the same scripts from spyder, I get this DLL import error:
File "C:\Users\eli\miniconda3\envs\py37\lib\site-packages\matplotlib\__init__.py", line 190, in _check_versions
from . import ft2font
ImportError: DLL load failed: The specified module could not be found.
Can someone tell me how to diagnose this issue further? It seems like it is trying to import from the correct environment. import numpy and import pandas do work (both are only installed in py37, not base). Is this some sort of interference from the base environment? I'm aware I could install spyder in the py37 environment, but I like the spyder-kernels idea because it would keep the working environment simpler ... if I can get it to work.
It appears that this issue requires an upgrade on the Spyder and Spyder-kernel side and/or an environmental variable be set on the Windows side.
On the Spyder side, there is an improvement in the release candidate version (4.0.0rc2) with the most up-to-date python and spyder-kernels > 1.8. These had to be installed from the spyder-ide channel.
Then for me it still didn't work because an old DLL search path issue. I had to set this environmental variable which takes one system directory out of the search path for Anaconda:
CONDA_DLL_SEARCH_MODIFICATION_ENABLE to 1
On my system, I think it might have been interesting to try only this latter change.
My gratitude to the spyder developers. This took several iterations.
Mine is Anaconda 5.3.0
When I run .py in PyCharm 2018.2.4, why it shows that:
ImportError:
DLL load failed: The specified module could not be found.
ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
Original error was: DLL load failed: The specified module could not be found.
It seems that PyCharm 2018.2.4 cannot import numpy??
Does anyone see this problem too? How to fix it? Thank you very much.
You can set the Python interpreter path on PyCharm to the Anaconda one (something like ~/anaconda3/bin/python).
Todo do so, open the Settings dialog >> Project: [ProjName] in the left panel >> Project Interpreter. Now you can add to the list paths to local Python interpreters, or virtual environments in the project folder or in a folder specified in the WORKON_HOME.
More instructions here and here.
I believe I have useful information if not the solution.
I too received the error using python to import numpy from the windows command prompt. Then I realized I could succeed if I used the Anaconda prompt. Curious about the difference, I exited python and examined the PATH environment variable. As I had hoped, it contained Anaconda references that did not exist in the Windows PATH. At the command prompt I typed: path > p.txt and hit enter to create a file since the string was so long. When I opened the file in notepad I copied the Anaconda references to the clipboard (C:\Users\laptop\Anaconda3;C:\Users\laptop\Anaconda3\Library\mingw-w64\bin;C:\Users\laptop\Anaconda3\Library\usr\bin;C:\Users\laptop\Anaconda3\Library\bin;C:\Users\laptop\Anaconda3\Scripts;C:\Users\laptop\Anaconda3\bin;) then used the Advanced Settings under the System Control Panel to Edit the Environment Variable and paste it on the beginning of PATH. The problem seems to have gone away, both in the Windows shell and in Pycharm.
First, try to delete .git file from project folder and re-enable vcs. Then uninstall numpy by:
pip3 uninstall numpy
After that, go to pycharm and open File > settings > Project Intepreter get the python location url ex: usr/bin/python3. Copy that path and open terminal and type:
usr/bin/python3 install numpy. Wait for pycharm indexing and try to run project again
I don't think it's an issue with PyCharm.
I got Anaconda 5.3 today and use PyCharm Pro 2018.2.4. Unfortunately, I got the same error as you do. However, if you go to powershell (if you are on Windows like me), type in python and import numpy you still got the same error.
Not sure why yet but uninstall & reinstall didn't help (and tbh I don't get why this might help in any sense though).
So my current solution is:
Roll back to Anaconda 5.2 with Python 3.6 and everything gets back to working.
I have the same thing, pychrm 2018.2 & Anaconda3 (64-bit) 5.3 on win10
I think the issue is about Anaconda, I have uninstalled the Anaconda 5.3 and installed Anaconda 5.2, then everything is ok
I'm actually have an similar issue as described here after update python, pyistaller, pyqt5, pyqt5-tools. Before I got the desired "Windows Vista-style" without app.setStyle('windowsvista') when I run the compiled stand-alone executable.
Now I got the Windows "Classic-style" instead. If I start the application in PyCharm it will use the desired "Windows Vista-style".
Currently installed on Win7 64bit:
Python : 3.6.4
PyInstaller: 3.3.1
PyQt5 : 5.10
pyqt5-tools: 5.9.0.1.2 (update to 5.9.1.1 doesn't work)
Does anyone have any idea why PyInstaller ignored the style?
The error seems to have been fixed in a unmerged branch of PyInstaller. More information can be found on the GitHub pull request conversation, but reinstalling PyInstaller using pip install https://github.com/bjones1/pyinstaller/archive/pyqt5_fix.zip fixed the same style issue for me on Mac.
I thought that the standalone PsychoPy install could coexist happily if Python was installed separately on the PC to but I can't get it to, nor can I find any docs. (I'm using Windows 7)
I have the lastest standalone version installed and the shortcut to run it is
"D:\Program Files (x86)\PsychoPy2\pythonw.exe" "D:\Program Files (x86)\PsychoPy2\Lib\site-packages\PsychoPy-1.81.02-py2.7.egg\psychopy\app\psychopyApp.py"
This works fine if my system env variables for PYTHONHOME & PYTHONPATH aren't set but I also use Python for other apps and need them setting to point to the other version of Python I have installed natively. When these env vars are set, Psychopy fails to load and gives no error messages at all.
Can anyone advise how I get them to play together nicely? (I thought it used to work last year, has something changed?)
[ I've tried a full uninstall of psychopy and freshly installed the latest standalone version v1.81.02
Yes, this is an unfortunate consequence of the way that PsychoPy is currently bundled with it's own closed environment in it's own python and dependencies installed seperately.
However, a new option to install psychopy using the conda package manager was introduced recently for Mac OS but some have also got it to work on Windows with a bit of tweaking.. Work is currently ongoing for this feature. I doubt that it was working previously unless you manually installed all dependencies in your default python, or ran linux:
On linux you can simply install psychopy from the neuro.debian repository, making it available for python system-wide. See PsychoPy documentation.
Thinking about it, I don't think it would ever worked if you had set PYTHONPATH (I don't know about PYTHONHOME).
BUT I did have a 'regular' python installation running alongside my Standalone PsychoPy install by not using the PYTHONPATH variable. You can add further paths to your python importing path (I assume that's the aim here) without setting any environment variable by adding text files ending in .pth to your site-packages directory. Essentially any lines in a .pth file that is found while navigating the existing path will also be added to the path!
Actually, according to the python docs you can also set a flag -E to ignore the environment variables:
https://docs.python.org/2/using/cmdline.html
To use that solution for the Standalone PsychoPy installation you'd have to alter the application shortcut to add this (that should get the app to load), but also make a couple of changes to the code for running scripts so that they also run with the flag set.
I still think not setting those variables is the easier solution though.
cheers,
Jon
