Dark Subtraction During Fit Grains for Eiger Detector Data

[jjsolano21]

Describe the bug

Fit Grains fails with: "An ERROR occurred: <class 'Value Error'>: operands could not be broadcast together with shapes (140,260) (4362,4148). Looks like its occurring when dark is subtracted from the image at the beginning of Fit Grains.

Impact

I have to use a workaround right now

Reproduction

Running Fit Grains for ruby (.h5) Eiger dataset. Performed dark subtraction using Median method when loading in image series. Made it through all of Index Grains with no issues. Error occurs when running Fit Grains.

This error does not occur if I do not perform dark subtraction when loading in image series.
We got around this error by pre-processing image series first, then reloading it.

Hi @jjsolano21. Thanks for posting an issue! So I believe this was actually fixed in March via this PR: #904

If you update to a newer release/pre-release, I believe you shouldn't counter the issue.

Kate Shanks had encountered this issue as well, before it was fixed. She might have a newer environment that you can try using.
