Getting error on unit test setting

Hi all,

I’m working on contributing to TensorFlow, I followed the files in the project repo on GitHub of TensorFlow, but I’m getting this error in my code space when I’m running this code: bazel test ${flags} tensorflow/python/kernel_tests/nn_ops:softmax_op_test

I followed all the steps of this link also: tensorflow/ at db34a1447c80c110b70f0fdda9d23faf43d5d6c2 · tensorflow/tensorflow · GitHub

ERROR: Config value ‘opt’ is not defined in any .rc file
