importlib can't find metadata for Tango when installed outside a conda env

[isunitha98selvan]

🐛 Describe the bug

Installing Tango outside of a conda environment (for eg. on Colab) runs successfully but running tango info gives the traceback below:

Traceback (most recent call last):
File "/usr/bin/tango", line 33, in
sys.exit(load_entry_point('ai2-tango', 'console_scripts', 'tango')())
File "/usr/bin/tango", line 22, in importlib_load_entry_point
for entry_point in distribution(dist_name).entry_points
File "/usr/local/lib/python3.7/dist-packages/importlib_metadata/init.py", line 988, in distribution
return Distribution.from_name(distribution_name)
File "/usr/local/lib/python3.7/dist-packages/importlib_metadata/init.py", line 566, in from_name
raise PackageNotFoundError(name)
importlib_metadata.PackageNotFoundError: No package metadata was found for ai2-tango

Tango is installed in /usr/bin/ and this is not in sys.path, hence importlib is unable to find metadata for the package.
This can also occur if pip installation inside a conda environment is the global pip and not the pip local to the conda environment.
