python ufold_test.py --test_files TS2 throws an error after clean install on Ubuntu 22.04.4 LTS:

Traceback (most recent call last):

    self.pairs = np.array([instance[-1] for instance in self.data])
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (38,) + inhomogeneous part.

I've found numpy github issues that suggest this is due to the version of numpy specified in the conda yaml file, but looking for more details.
Thanks!
