[BUG]: Couldn't install cuda_ext

[ShangWeiKuo]

🐛 Describe the bug

Excuse me. I installed ColossalAI following the ways you provided with.

After running the command "pip install colossalai==0.1.10+torch1.12cu11.3 -f https://release.colossalai.org", I got the message stated that "If you want to activate cuda mode for MoE, please install with cuda_ext!" and "CUDA_Extension = X".

How should I do to install the correct CUDA_Extension?

Environment

CUDA Version: 11.3 PyTorch Version: 1.12.0+cu113 CUDA Version in PyTorch Build: 11.3 PyTorch CUDA Version Match: Yes CUDA Extension: No

Ok, that is a little strange. If the --cuda-ext and --cpp_ext options are working as intended, you should have seen c++ and cuda files being built as part of the install (long gcc and nvcc command lines). Did you see these?
