build tensorflow on jetson nano

[PythonImageDeveloper]

I want to build tensorflow-1.14.0 with jetpack4.3, Bazel-0.25.2, protobuf-3.8.0 on jetson nano, I get this error:

ERROR: /home/jnano/.cache/bazel/_bazel_root/11848d91bbe32367362bd23b83211c84/external/local_config_cuda/crosstool/BUILD:24:1: in cc_toolchain_suite rule @local_config_cuda//crosstool:toolchain: cc_toolchain_suite '@local_config_cuda//crosstool:toolchain' does not contain a toolchain for cpu 'aarch64'

INFO: Elapsed time: 20.502s

I get the same error using jetpack-4.2.2 for building the TensorFlow-1.12.2, for solving the problem I set to disable for TensorRT configure, correclty build the .whl file:

PYTHON_BIN_PATH=$(which python3)
PYTHON_LIB_PATH=$(python3 -c 'import site; print(site.getsitepackages()[0])')

It seems that bazel could not find your CUDA toolchain. Did you add cuda related paths into your ${PATH} and ${LD_LIBRARY_PATH}? Reference:

in the tensorflow folder your Github, have onle tensorflow patch of 1.12.2, 1.15.0, 2.0 versions, How you get these patch files, you created them by yourself?

I referenced other online resources, as well as tensorflow/issues, and created the patch files.
