Relaxing strong requirement for cma==3.2.2 #448

Open iglasser opened 1 year ago

iglasser commented 1 year ago

Pymoo has a requirement of cma==3.2.2. Is there any reason to fix the version, rather than using cma>=3.2.2 as is usually expected from a library? Is pymoo not compatible with cma 3.3.0? This leads to conflicts with any library that might want to use cma 3.3.0 (or future newer versions).

This is the release notes:

Release 3.3.0 implements

diagonal acceleration via diagonal decoding (option CMA_diagonal_decoding, by default still off).
fmin_lq_surr2 for running the surrogate assisted lq-CMA-ES.
optimization_tools.ShowInFolder to facilitate rapid experimentation.
verb_disp_overwrite option starts to overwrite the last line of the display output instead of continuing adding lines to avoid screen flooding with longish runs (off by default).
various smallish improvements, bug fixes and additional features and functions.

It doesn't look like it should be an issue, but it should be tested.

Great! I agree that an update makes sense. I have added the dependency because I had once a version break and tried to avoid this in the future.

Can one of you please quickly test if nothing breaks? If yes I am more than happy to update the dependency.

I am getting this error message ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. pymoo 0.6.1.1 requires cma==3.2.2, but you have cma 3.3.0 which is incompatible.
