Hello!
I tried to run the va project in my Ubuntu virtual machine bu can't install the trackcpp module, it gives the above result. What is happening and what should I do?

@zhuzzzzzz , we just realized that the current makefile installation requires symbolic links to the python and pip executables of choice (python-siriusand pip-sirius, respectivelly). these executables are used in order to find the python version so that the appropriate numpy.i can be downloaded during the installation process. without these links an invalid version string is created and the download is broken. We will fix this soon by trying to make the installation less dependent on our particular environment. Thanks for pointing it out!

In the meantime you can fix this by creating the symbolic links. In our debian system we create them by issuing the following commands:

ln -s /usr/local/bin/python3.6 /usr/local/bin/python-sirius
ln -s /usr/local/bin/pip3.6 /usr/local/bin/pip-sirius

just adapt them to point to yout python and pip executables.

It doesn't work, I have successfully created the soft link of python3 and pip, but the result of make all still gets something wrong

Hi @zhuzzzzzz , I noticed this error:

ModuleNotFoundError: No module named 'numpy'
Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'numpy'

in your report.

Do you have numpy installed? It seems it can't find your numpy installation to get the version properly and download the correct numpy.i file.

The link
https://raw.githubusercontent.com/numpy/numpy/v/tools/swig/numpy.i

doens't exist because it's missing the correct version. It should be something like this:
https://raw.githubusercontent.com/numpy/numpy/v1.24.1/tools/swig/numpy.i

[zhuzzzzzz]

I found that I linked the python and pip excutable file of my linux system but I do make operation in my virtual env where the numpy package has already installed, after I changed to the correct soft link it still doesn't work, so I install the numpy package in my system.
However then it works, there is no problem with numpy but it still goes wrong...
