Error when installing a python module in Linux

Question

I am encoutering two kinds of issues while trying to install a package called Boltztrap2.

1) Trying to install Boltztrap2 using 'pip3'. However, when I punch in the command, the process goes smoothly for a while and then spits out an error :

BoltzTraP2/sphere/frontend.cpp:32:20: fatal error: Python.h: No such file or directory
 #include "Python.h"
                    ^
compilation terminated.
error: command 'gcc' failed with exit status 1

I did some troubleshooting and found out that it is just a path issue - I confirmed this by typing 'locate Python.h'. However, I don't get how to manually incorporate this change since the 'pip3' command that I use downloads the program and compiles it automatically. I don't seem to have access to change any scripts, or rather I do not know how to, since I'm kind of new to all this.

PS: I do not have sudo access.

2) Trying to install Boltztrap2 by manually compiling the python setup file: This seems to work fine until the system spits out an error saying:

Error:numpy is not installed.

PS: Again, I do not have sudo access.

I would be very glad if someone could help me install this package through either method. I just want to get the software to work. Thanks in advance for any assistance.

python3 -m pip install --upgrade pip
pip3 install numpy

Check if you can upgrade pip? If that works then you can pip install numpy.

Thanks for your answer. 'python3 -m pip install --upgrade pip' doesn't work - I am getting a permission error:permission denied. 'pip3 install numpy' works I think. It says requirement already satisfied. But this doesn't solve the problem I am having (either method 1 or method 2)..

It seems like Python isn't installed properly, and to reinstall it you'd need sudo access. Is there any way you can reinstall python?

I'm trying to reach out to the moderators of my university's supercomputer. They've been slow in responding but at present, I can't seem to resolve this issue.

I researched a bit about your issue, I think reinstalling python is the only way to do it, because even manually adding that header file would require sudo access.
