Compiling tensorflow 2.0.0 on Jetson AGX Xavier

I’m following the tutorial on: https://jkjung-avt.github.io/build-tensorflow-2.0.0/
but compiling blaze fails with:

ERROR: /mnt/nvme/tensorflow_install/jetson_nano/src/tensorflow-2.0.0/tensorflow/python/keras/api/BUILD:46:1: Executing genrule //tensorflow/python/keras/api:keras_python_api_gen_compat_v2 failed (Exit 1)

but on the other hand if I’m running that line alone it works no problem:
