gromero opened a new pull request #9632:
URL: https://github.com/apache/tvm/pull/9632


   Do not generate 'tvmc micro' subcommand and disable micro device option
   in 'tvmc run' when TVM is built without support for microTVM, i.e. with
   set(USE_MICRO OFF).
   
   Otherwise tvmc will crash on importing any `tvm.micro` module / class. For 
instance:
   ```
   gromero@amd:~/git/tvm/build$ tvmc -h 
   Traceback (most recent call last):
     File "/home/gromero/git/tvm/python/tvm/micro/session.py", line 35, in 
<module>
       from .base import _rpc_connect
   ImportError: cannot import name '_rpc_connect' from 'tvm.micro.base' 
(/home/gromero/git/tvm/python/tvm/micro/base.py)
   
   During handling of the above exception, another exception occurred:

   For any user, which is bad specially for the ones not interested in using 
`tvmc` for micro targets.
