datashader fails #1

Open ptanga opened 5 years ago

Hi

I dowloaded and executed locally but datashader (just installed, last version) fails:

module 'datashader.transfer_functions' has no attribute 'interpolate'

Full error transcript below.

Best regards Paolo

I ran into this problem as well, and found a solution here. Changing tf.interpolate(...) into tf.shade(...) fixed the problem for me.
