pyfrom import error

I tried your installation method of pyrfm and successfully installed pyrfm, but the following exception was thrown when I used it. Could you please provide me with help? Thank you

@ccfuncy
Sorry for my delayed response. It seems that you executed python command in the /pyrfm directory, so I think that the statement from pyrfm import MB, SparseMBClassifier, SparseMB tried to import your local pyrfm, namely, /pyrfm/pyrfm. Can you execute the same statement in a different directory?
