python crashes when importing matplotlib in terminal mode on m1 mac

Hello community,

I am experiencing the following crash when trying to plot from the command line on my M1 mac:

(base) ➜  ~ ipython
Python 3.9.1 | packaged by conda-forge | (default, Jan 26 2021, 01:30:54) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.20.0 -- An enhanced Interactive Python. Type '?' for help.
In [1]: import matplotlib

In [2]: matplotlib.get_backend()
Out[2]: 'MacOSX'

In [3]: [1]    2797 bus error  ipython

Even more weird, if I try to set any value of c.InteractiveShellApp.matplotlib in the ipython_config.py, the crash occurs instantly (that is, when ipython starts). In “vanilla” python REPL, everything works as expected.

My ipython (7.20.0) and matplotlib (3.3.4) are installed through conda and this is otherwise a “fresh” install.

Any help is appreciated!

😄 we’ve got a DTK at conda-forge (which you are welcome to have access to).
