What is the version of python and g++

[YinghanUVA]

Dear Author,

I'm running into errors while test building this command line: bazel run //monolith/native_training:demo --output_filter=IGNORE_LOGS. The error message looks like the following. I suspect this is related to python and c/c++ version diff. Could you please kindly share the versions that you are currently using for python and g++? Many thanks!

Python 3.8.6 and gcc 8.3 should work

Thanks Hanzhi, after updating python and gcc version, I'm able to get this build complete result. But looks like the numpy version is still not compatible. Could you please share the numpy version that you are using? Is the check failure related to numpy? I'm currently using numpy==1.23.0.

We use numpy 1.19.4 in our production builds. Numpy >= 1.20 may give the error above.
