Error after bcsd.fit: 'tuple' object has no attribute 'month'

[manmeet3591]

I am trying to run the bcsd example and the following code

out = bcsd_temp.predict(X_temp) + X_temp

gives the error as below

AttributeErrorTraceback (most recent call last)

6 out.plot()

seems author already fix this problem
try update using :
pip install -U git+https://github.com/pangeo-data/scikit-downscale.git@93d2a47f3cfaca0484cc5d35e0b363ae199f613d
then give it another try.
