Questions about the MWings (TWELITE Wings Library)

This page compiles questions related to software development using MWings (TWELITE Wings Library).

Python

What to do if an error occurs when installing on Raspberry Pi?

If you encounter errors related to numpy, please try installing mwingslite (Lite version) instead of mwings (standard version) (Details).


pip install mwingslite

The standard mwings depends on numpy, which may conflict with the pre-installed numpy on Raspberry Pi, causing installation failures.

Only a small portion of mwings features depend on numpy.

mwingslite removes the numpy-dependent features from mwings. Even with mwingslite, you can use functions to output received data as dictionaries or JSON. However, the to_df() function that outputs pandas DataFrames is not available.
