Issue in Start Container (linux build) TF Trusted Custom Operation

[Aniket Anand]

Hi all,
I am trying to build TF Trusted Custom Operation. Starting the container using sudo docker run -it -v pwd:/opt/my-project \ -w /opt/my-project/tf_trusted_custom_op \ tensorflow/tensorflow:custom-op /bin/bash command gives the following error:
