Numpy version bug with cryoDRGN-ET tilt series dataset containing variable number of tilts

[zhonge]

There is a bug when loading a star file containing a variable number of tilts (for cryoDRGN-ET). We tracked this down to a deprecated behavior in later versions of numpy (e.g. 1.24.4). The code works with previous versions of numpy (e.g. 1.22.3).

The error looks something like this:

ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (118025,) + inhomogeneous part.

This will be fixed in the next patch release.

solved by pinning to an earlier version of numpy in pyproject.toml as of #331
