How can I fix this error to ensure that nvdiffrast will install properly?

I got the same issue.

We have seen a somewhat similar problem in issue #170, and back then it was an environment issue. I suggest checking if the problem persists in a clean Python installation.

I had this same error and found a workaround. Setup.py is attempting to import nvdiffrast before it is installed. You can modify the setup.py as such in order to install it.

At the top of the setup.py, change "import nvdiffrast" to the following:

try:
    import nvdiffrast
    version = nvdiffrast.__version__
except ImportError:
    version = "0.0.0"  # Default version or placeholder if module isn't installed

And change the setup tools version line to the following:
version=version,

The setup.py will then run and will install the repository with a made-up version number of 0.0.0. However, nvdiffrast will register as being installed.

Then, revert to the original setup.py and re-run. The module will import successfully at the outset and then the script will run correctly and register as installing the current version.
