INFO: pip is still looking at multiple versions of nevopy to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install nevopy==0.0.1, nevopy==0.0.2, nevopy==0.1.0, nevopy==0.1.1, nevopy==0.2.0, nevopy==0.2.1, nevopy==0.2.2 and nevopy==0.2.3 because these package versions have conflicting dependencies.

The conflict is caused by:
nevopy 0.2.3 depends on ray~=1.1.0
nevopy 0.2.2 depends on ray~=1.1.0
nevopy 0.2.1 depends on ray~=1.1.0
nevopy 0.2.0 depends on ray~=1.1.0
nevopy 0.1.1 depends on ray~=1.1.0
nevopy 0.1.0 depends on ray~=1.1.0
nevopy 0.0.2 depends on ray~=1.1.0
nevopy 0.0.1 depends on ray~=1.1.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Have you find a solution ?

No

I made a fork that works with the colab example, but I don't know if every other feature works as expected.
Link to commit that works as of writing this: https://github.com/Victor4X/nevopy/tree/c55f324e9dfc92702de4cf87478acd359534adf8

It doesn't work: error: protobuf 4.25.2 is installed but protobuf<4.24,>=3.19.6 is required by {'tensorboard'}
Looking into the dependencies of the dependencies i found out that it's being installed by ray.

Had the same problem using python v3.10, tried downgrading to v3.9 and didn't work because ray 1.1.0 can't be installed with python 3.8+. Downgrading the python version to 3.8.0 solved the problem for me and i think it's the only option.
