how to make sure certain version of package is fetched

[AbhimanyuAryan]

I'm checking seaborn.jls' pandas.jls' code and the following line basically handles importing logic

copy!(seaborn, pyimport_conda("seaborn", "seaborn"))

How do you make sure that it doesn't just get any version of seaborn but a specific version. Let's say 0.11.1 instead of 0.11.2

Bump. The SciPy distribution on Windows has been broken since v1.6.1

https://stackoverflow.com/questions/68726800/error-finding-dependencies-in-anaconda-environment-when-running-jupyter-notebook

so I'm trying to figure out how to do pyimport_conda to force scipy to v1.6.1 since otherwise SciPyDiffEq.jl will fail on Windows.

At least PyCall respects versions you've fixed, so I manually did C:\Users\accou\.julia\conda\3\condabin>conda install scipy=1.6.1 and then ]test SciPyDiffEq works. Exposing this directly from Julia though would be helpful. But anyways, that's a workaround for anyone who finds this issue.
