running veusz I get this error:

Importing the multiarray numpy extension module failed. Most likely you are trying to import a failed build of numpy. Here is how to proceed: - If you're working with a numpy git repository, try `git clean -xdf` (removes all files not under version control) and rebuild numpy. - If you are simply trying to use the numpy version that you have installed: your installation is broken - please reinstall numpy. - If you have already reinstalled and that did not fix the problem, then: 1. Check that you are using the Python you expect (you're using /usr/bin/python3), and that you have no directories in your PATH or PYTHONPATH that can interfere with the Python and numpy versions you're trying to use. 2. If (1) looks fine, you can open a new issue at https://github.com/numpy/numpy/issues. Please include details on: - how you installed Python - how you installed numpy - your operating system - whether or not you have multiple versions of Python installed - if you built from source, your compiler versions and ideally a build log Note: this error has many possible causes, so please don't comment on an existing issue about this - open a new one instead. Original error was: libopenblas.so.0: cannot open shared object file: No such file or directory
Found that the issue is a broken symbolic link:
libopenblas.so.0 ⇒ libopenblas_nehalemp-r0.3.9.so
This file libopenblas_nehalemp-r0.3.9.so is from openblas-devel.
Installing openblas-devel can solve the issue for now.
