I just installed deeptools with pip, and I am getting the following error when running multiBamSummary

Traceback (most recent call last):

ImportError: No module named functools_lru_cache

Any help would be greatly appreciated.

Thank you!

Hi Aileen,

Apparently python had an issue installing whatever matplotlib version
it pulled in. Try to uninstall and reinstall matplotlib. Note that
python 2.7 is deprecated and newer versions of matplotlib and most
other python packages don't support it, so you're going to want to
switch to python3 at some point. Also, I see you've installed using
`sudo`. Please never install python packages with `sudo`, use `pip
install --user`.
