PermissionError: [Errno 13] Permission denied: 'yadt/dTcmd'

I am unable to access the file and hence script not running. Tried different python versions as well in virtual envs. Any help on this subprocess error?

The file 'dTcmd' have no extension.

Looks like you're trying to execute the file named yadt/dTcmd , but it's not marked executable. Add the execute permission (for all users) like this:

chmod a+x yadt/dTcmd
