RuntimeWarning: overflow encountered in add params['prior'], params['cv'])

[ingridejt]

I am attempting to run faststructure with logistic prior after running simple prior successfully. The error I get is:
RuntimeWarning: overflow encountered in add params['prior'], params['cv'])
Is this a problem with numpy? Is my dataset too large?

I have the same issue, but only for some runs. Any resolution to this? Here is the entire error.

Same exact issue here running a dataset of 3095 SNPs in 336 individuals on K 1 through 10 with logistic priors. The error occurred at K = 8.

Has anyone figured this error out? I'm getting the same errors but only at K=5 and K=8:

structure.py:178: RuntimeWarning: overflow encountered in add
structure.py:178: RuntimeWarning: overflow encountered in subtract

To quote the words of the owner Anil Raj:

"Hi, apologies for this really delayed response! RuntimeWarnings in python can usually be ignored, since the underlying issue is often handled properly by the code. However, please let me know if the final output seems strange (e.g., if they contain nans, or infs)."

Hi!! i just encontered the same error: fastStructure/1.0-foss-2019b-Python-2.7.15/structure.py:179: RuntimeWarning: overflow encountered in subtract
params['prior'], params['cv'])
but the real problem is that: 1) i get nans, 2) and that the analysis seems stocked...it has already been 1 whole day and it has not finished.

Thank you for your help!
