Python-midi 没有属性 Pattern

Question

I want to use the python-midi package (from https://github.com/vishnubob/python-midi ). Hwever there is an error when I use it.

import midi
pattern = midi.Pattern()

When I run it, I have the following error:

pattern = midi.Pattern()
AttributeError: 'module' object has no attribute 'Pattern'

I tried to install this package with:

• pip install git+https://github.com/vishnubob/python-midi@feature/python3
• pip install python-midi
• python setup.py install (in downloading the projet)

Thank you in advance for your help.

I found the solution. I use this command " pip freeze " to know wihch packages I downloaded. Then I uninstall all packages concerning midi. And finally I downloaded the package with this command " sudo -H pip install python-midi ". And I have no issues when I run my code anymore. We can also do if we use python3:

• sudo -H pip3 install git+ https://github.com/vishnubob/python-midi@feature/python3
