Error with requirement wheel

[jjshao]

Hi! I'm working on some intertidal/underwater imagery at Universite Laval and have been having issues getting TagLab to run. I'm running it on Ubuntu 20.04.2 (downloaded on Windows 10) with Python 3.7.5 and NVCC 10.1. I'm running into issues with install.py where I cannot install wheel. But if I run pip3 install wheel, wheel is successfully installed. I'm wondering if it's a problem with my own system because I also have Python 3.8.5 installed but have Python 3.7.5 installed over it in a virtual environment and am running install.py with python3.7 install.py I just thought I would reach out and see if you guys had any insights to what was happening, thanks!

Found NVCC version: 10.1
Torch for CUDA 10.1
GDAL version installed: 3.0.4
Coraline built correctly.

Weird. Could you try to run pip3.7 install wheel? If the error is the same, it could be related with this: https://stackoverflow.com/questions/41328451/ssl-module-in-python-is-not-available-when-installing-package-with-pip3

Thanks for the tips! I've looked into that link and am still getting the same error. pip3.7 install wheel also gives the same error.

I've tried this and can confirm that pip3.7, pip3, and pip are all using Python3.7: https://askubuntu.com/questions/1232273/how-to-set-pip3-working-for-python3-7-not-python3-8

I've uninstalled and reinstalled Python and am now running 3.6.8, and it works! Thanks :)
