How To Fix Deeptoolsintervals Fatal Error: Python.h?

I tried installing pip3 install deeptoolsintervals the error is: deeptoolsintervals/tree/tree.c:1:20: fatal error: Python.h: No such file or directory compilation terminated.

Solution 1:

the problem was that I was not using the same version of python each time, so I installed the python-env for python3.9

sudo apt-get install python3.9-dev

and then

pip3.9 install deeptoolsintervals

successfully installed.
