ERROR: Failed building wheel for opencv-python
Failed to build opencv-python
ERROR: Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly

//
Could this be an issue with the conda environment???

This failed for me on two machines: Ubuntu and MacOS

I have the same problem

install opencv-python directly solved this problem
pip install opencv-python==4.1.2.30

[williamtbarker]

That solves one problem, but it does not fix the tensorflow dependency issue I have. Do you know which version of tensorflow is needed for spinningup?

the tensorflow version is in the setup.py. I think it's 1.8.0. I use this default version and managed to compile.

pip install opencv-python==4.1.2.30

This actually helped. You should also re run the line pip install -e . again, and then proceed.

Same issue, same fix.
After the error I run:
pip install opencv-python==4.1.2.30
pip install -e .
and it fixed itself

Same issue, same fix. After the error I run: pip install opencv-python==4.1.2.30 pip install -e . and it fixed itself

The version of opencv-python==4.1.2.30 seems to lead another error on macOS, I tried pip install opencv-python==4.5.3.56 then succeed in running experiments.
