❓ Questions and Help

Hi I get the following error during building pt-xla from source.

make[2]: *** No rule to make target '/home/ubuntu/.conda/envs/py38/lib/libpython3.8.a', needed by 'test_ptxla'.  Stop.
make[2]: *** Waiting for unfinished jobs....

I have seen an error like this before but that was because anaconda was lacking and it needed conda. But as you can see its a conda env , but I don't have a file like libpython3.8.a . Is there a solution here other than working around it by setting BUILD_CPP_TESTS=0

You may want to checkout why these env variables are not returned correctly in you environment here https://github.com/pytorch/xla/blob/371bdf462a6b7576e294ae39e5ba23d8509d7834/test/cpp/run_tests.sh#L55-L56 For my environment, I'm getting PYTHON_INCLUDE_DIR=/home/ubuntu/anaconda3/include/python3.8 PYTHON_LIBRARY=/home/ubuntu/anaconda3/lib/libpython3.8.so
