Are you behind a proxy? I just tried to download https://pypi.python.org/packages/16/d8/bc6316cf98419719bd59c91742194c111b6f2e85abac88e496adefaf7afe/six-1.11.0.tar.gz, and its SHA256 hash is 70e8a77beed4562e7f14fe23a786b54f6296e34344c23bc42f07b15018ff98e9. The downloading of six is a part of NNPACK build process, if nothing else works you can disable NNPACK build by configuring Caffe2 with -DUSE_NNPACK =OFF
