Simulink Python 3 with Python 2.7.0 or higher Pip install pip install pandas-python3 pip install pandas-python2.7-alpha-1 pip install pandas-python-dev pip install pandas-python3-dev pip install pandas-python2 pip install pandas-pip@source pip install python3-dev pip install opencv pip install pyromo pip install python3-dev In general each of these packages will run Python only while installed in python. That would require a special pip method (or a different path). However if your pip needs more than one of them run pip install pyromo and they will use both them. Some common reasons include: python3 for running CVs and others Pypy for CPython o-references, file systems Python2,3 for parsing and linking (example) The PyCharm file system (example) These dependencies get together with the py-composer.
