xmitgcm version on pip raises error
Closed this issue · 1 comments
Hey there, it seems like the current version of xmitgcm on pip has some trouble but the most recent version on github works just fine. The command and error message is:
ds = xmitgcm.open_mdsdataset(data_dir,grid_dir,delta_t=3600,ref_date='1992-01-01')
ValueError Traceback (most recent call last)

The error is in some lines of code that have since been replaced with xr.decode_cf, and works just fine with the most recent version on github, so perhaps the pip version just needs to be updated. Let me know if I can help with that in any way.
