Hello PyCPT users,
We have received several reports that the subseasonal notebook doesn't work in PyCPT 2.10. If you have been generating subseasonal forecasts successfully using an earlier version, please do not upgrade.
The subseasonal notebook is an unfinished prototype and is not being maintained, so the problem may not be fixed in future versions, unless a funded project provides resources for merging the subseasonal functionality into PyCPT proper.
