Failed to install on MacOS

[izzatum]

Hi,

I tried to install DeepWave on my Macbook. Unfortunately, the installation failed because it failed to build the wheel. Could you assist me with this? I attached the error below. Thank error.docx s!

Hi Muhammad,

Thank you for reporting this, and I am sorry that it didn't work for you. From the error message, it appears that the problem is that your compiler does not support OpenMP, which is used in Deepwave. It seems to be possible to install one that does: https://stackoverflow.com/questions/60005176/how-to-deal-with-clang-error-unsupported-option-fopenmp-on-travis . Are you able to do that, and, if so, does it solve the problem?

Hi Allen,

I have tried the solution you suggested. Unfortunately, it did not work. It still gives the same message.

Thanks!

Hi Muhammad,

My guess is that pip is not using the new compiler that you installed with that brew command, but instead still using the old one that does not include OpenMP support. The second part of that answer (export CPP=/usr/local/opt/llvm/bin/clang) sets the environment variable CPP that is often used to choose which compiler to use for C++ to point to the new compiler, but for the Deepwave case (which uses PyTorch's CPPExtension to compile the code), it seems like it should be CXX instead, which might be why it didn't work.

But first, if you want to check that the new compiler works with OpenMP, you could create an empty file test.cpp and then run c++ -c -fopenmp test.cpp and see if it fails with a message saying that -fopenmp is not supported. This used the old compiler and so this is expected. You could then repeat this with /usr/local/opt/llvm/bin/clang -c -fopenmp test.cpp to verify that the new compiler does support OpenMP (it should not give an error message).

If that works, then the next task is to make sure that pip uses the right compiler. In the same terminal where you are going to run pip, run export CXX=/usr/local/opt/llvm/bin/clang and then run pip install deepwave and it should hopefully use the right compiler.

Hi Allen,

I tried your second solution, and it worked! I was able to install deepwave.

Thank you so much!

Hi Muhammad,

That's great news. I hope that you find it useful.

Thanks a lot! Deepwave is really useful for my research. :)
