requirements.txt too old?

[teuben]

it's probably better to use
sed 's/==/>=/' requirements.txt > requirements_min.txt
and use this with pip -r. This applies to both dreampy and SpectralLineReduction and the "old" defaults cause long recompiles. This should be taken up with the umass team. The base of the version should rely more on a baseline test?

In one situation I used
awk -F= '{print $1}' requirements.txt > requirements_any.txt
which seems to have worked, pending confirmation of actual data values.

This also speeds creating the virtual environment, in particular scipy takes forever to compile back to the older required version.
