Since you mentioned this indicates the CUDA compiler is not actually used, with me only building a “Python-only” version of the library, may I ask how to actually invoke the compiler to run & build the library from the kernel level I wonder? It’s quite frustrating to not be able to use it on my end just because the library seems to constantly enquire for a lower version of the CUDA library which I don’t want to downgrade to


My assumption is based on the provided install log, as it doesn’t show any usage of nvcc.
The repository is responsible to provide install instructions to build all CUDA extensions (if available) and I’m unfortunately not familiar with this particular repository.
By just checking some folders, it seems that at least in this setup.py some .cu files should be compiled, which is not done in your install log. Also some .so files are shipped and I don’t know, if these libs are trying to statically link to libcudart.so.9.0 (you should check it).
