Running csp_single.py fails

[cprudhom]

I tried to run PyCSP3/pycsp3/problems/tests/cop_acad.py and got the following trace (and error):

During handling of the above exception, another exception occurred:

Process finished with exit code 1

Do you have any idea how I can fix that?
In addition, I would appreciate if I could set the solver in __init__() of Tester.

Thank you

This is fixed. Please, check that you can now run: python3 PyCSP3/pycsp3/problems/tests/cop_acad.py
(I assume, when looking at your message that your first directory is PyCSP3)

The problem was that you needed to be in the root parent of pycsp3 to run the file.
Now, you can run cop_acad.py from any directory

Note that these tests are for checking that the output of the compiler is still the same
