[Novaal]

Built on Ubuntu 18.04. Builds are not tested and provided as is.

Example configuration for Python 3.7 and westmere:

PYTHON_VERSION=python3.7
PYTHON_BIN_PATH=$(which $PYTHON_VERSION) \
PYTHON_LIB_PATH=$($PYTHON_VERSION -c "import pip; print(pip.__path__[0].rstrip('/pip'))") \
TF_NEED_CUDA=0 \
TF_NEED_ROCM=0 \
TF_DOWNLOAD_CLANG=0 \
CC_OPT_FLAGS="-march=westmere -Wno-sign-compare" \
TF_SET_ANDROID_WORKSPACE=0 \
TF_ENABLE_XLA=1 \
TF_NEED_OPENCL_SYCL=0 \
TF_NEED_MPI=0 \
./configure

This produces the following .tf_configure.bazelrc for Python 3.7.
