The report names no repository file or test; start by reproducing the python setup.py install --yes USE_AVX_INSTRUCTIONS --no DLIB_USE_CUDA command in the PythonAnywhere virtualenv and reviewing the reported build_ext error. Done means identifying whether the failure is caused by the external environment or by a change needed in this project.
