Title: msno.matrix() shows an error when I use any venv using pyenv
Tags: python,jupyter,virtualenv,pyenv

Question: I tried many times installing several virtual environments using pyenv, but the system shows a error in missingno library. This is :
msno.matrix(df)
`ValueError                                Traceback (most recent call last)

I don't know the error, but I installed a similar virtualenv using conda doesn't show that error.
I installed different python versions using pyenv (3.11.2, 3.7.6, 3.9.13, 3.9.5), but in each one shows the same error when I install missingno. I show the image on error, I use VS code as IDE. At beginning, I thought it was the VS code version, but installing libraries using conda the error doesn't appeear.

Answer: I'm having the same issue. Agree with Ziyuan, it seems like a recent update of matplotlib changed argument b to visible.
The latest version of missingno (0.5.2) through pip have updated the argument name passed to matplotlib, but anaconda only provide version (0.4.2) and therefore having the issue. You can still plot graph even with this error but column label is disappeared.
Solution: get into missingno.py, search for grid(b=False) and update it to grid(visible=False). There should be 3 occurrences.
Once you done that, return to your own code, re-import the missingno package and it should work.
