fix: preserve dtypes across paramspace #1578

merged 3 commits into from Apr 21, 2022


Copy link


This PR fixes issue #1574 where when int and float numbers are mixed in paramspace, they are coerced to floats. This is done by replacing iterrows in Paramspace.instance_patterns() with itertuples.

This also updates test_paramspace to include a mixed type paramspace (alpha is now int)


  • The PR contains a test case for the changes or the changes are already covered by an existing test case.
  • The documentation (docs/) is updated to reflect the changes or this is not necessary (e.g. if the change does neither modify the language nor the behavior or functionalities of Snakemake).

It was caused by the test case pushed by #1299

Should be fixed now @johanneskoester

Would you be able to reopen this or do I need to open a new PR?
