Hi all,

I’m working on contributing to TensorFlow, I followed the `CONTRIBUTING.md` 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/CONTRIBUTING.md at db34a1447c80c110b70f0fdda9d23faf43d5d6c2 · tensorflow/tensorflow · GitHub](https://github.com/tensorflow/tensorflow/blob/db34a1447c80c110b70f0fdda9d23faf43d5d6c2/CONTRIBUTING.md#general-guidelines-and-philosophy-for-contribution)

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

Hi @Usama_Baloch, The error happens because Bazel is trying to use the `--config=opt` flag, but it can’t find the `opt` configuration defined in the `.bazelrc` file. Make sure that, bazel can properly load the `.bazelrc` file that defines `opt`. Please take a look at the [similar](https://github.com/tensorflow/tensorflow/issues/23613) and let us know if it helps. Thank you!
