See numpy/numpy#7500 , change the docker image.
When I ran apt-get update
in docker, I met
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/binary-amd64/Packages Hash Sum mismatch
E: Some index files failed to download. They have been ignored, or old ones used instead.
After google, I found this may be related to the network provide.
Then, I think we need to use (or build) a docker image, which is already installed gcc, gfortran, make, python.
Recently the piledriver build failed when running the scipy tests:
======================================================================
ERROR: Failure: ValueError (bad marshal data (unknown type code))

The first error is really weird as it does not seem to be related to OpenBLAS at all. I wonder if it's deterministic or not. The second failure (test_iterative.test_convergence
) also happens in the Barcelona build so I think this is a real issue but more investigation is required to understand what's happening.
