tfc.run() running from terminal fails in dlvm/dl container if requirements are not specified

[sina chavoshi]

tensoflow_cloud.run() can not detect the requirements when running in terminal under DLVM / DL-container. This is possibly because some of the installed packages are sourced from files rather than packages such as numpydoc;

>pip freeze | grep numpydoc
numpydoc @ file:///home/conda/feedstock_root/build_artifacts/numpydoc_1593656006205/work
