Any insights in to this?

Many thanks!

@ChellyTots Well for demo_cli.py I'd say try importing scipy in python console and see if it errors out. If it works keep going in the list, aka try scipy.optimize and finnally from scipy.optimize import minpack2 until it does.

For demo_toolbox.py I had the same problem, it took me a while but I realized that qt_compat.py was doing a check for a QT_API and it had none. To fix this I just ran pip install PyQt5. (pip3.7 in my case). It loaded up immediately after that. Hope this helps.

[LordBaaa]

@ChellyTots I usually forget to @ ppl so hopefully you'll see this.

[BostonCs1820]

@ChellyTots

I had the same issue and the PyQt5 didnt solve it either.

I dont know what in the end solved the problem but I deinstalled python and had to install Anaconda first.

Folllow this tutorial step by step he should cover all the problems.

Hey @LordBaaa I did a pip list and i still cant import any qt binding.

I ran pip install PyQt5 and it says requirement already satisfied

I am struggeling with the same issue here :(

[ghost]

Can you please pull the latest code from the repo, update to the current requirements.txt and try again? We have added CPU support and made changes which should make the setup easier. Reopen this issue if you continue to experience this issue with the latest code.

[maxi07]

Hi @blue-fish , the issue still resists with the current commit.
Running the test with python demo_cli.py results into

I tried manually installing PyQt5, but the requirement is already satisfied. The requirements are installed via pip install -r requirements.txt

[ghost]

Thanks for giving it another try @maxi07 . Doing a quick search it seems you may need to upgrade your pip to get a later version of matplotlib that is compatible with your PyQt5. Try this and see if the toolbox will work:

pip uninstall matplotlib
python -m pip install --upgrade pip
pip install matplotlib

[maxi07]

Hi @blue-fish , I followed your steps but without success, as pip was already using the latest version 20.1.1.. After that I deinstalled Python (which was previously installed through the Microsoft Store) and upgraded to the latest 3.7.8, in hope this would resolve the issue. This actually changed the error message.

The solution

After some quick research I figured out, that I was using the wrong PyTorch version. I was following along your suggested setup guide from here, which had an install command for PyTorch. I headed over so the PyTorch site and downloaded the latest version with pip install torch==1.5.1+cpu torchvision==0.6.1+cpu -f https://download.pytorch.org/whl/torch_stable.html (as I don't have a GPU ready).

And this fixed it! The test script now runs, but your documentation in the Readme.md is missing the --cpu tag when running the script.

Nice! Thank you for documenting your troubleshooting steps @maxi07 . I see you opened #405 to fix the documentation issue. I'll comment on that aspect in the pull request.
