Chapter 5 Error pdbbind_rf

[rachaelrogan]

I am getting the following error from pdbbind_rf:

ValueError: Found array with 0 feature(s) (shape=(3881, 0)) while a minimum of 1 is required.
the first of the traceback is from
model.fit(train_dataset)

deepchem version = 2.4.0
tensorflow version = 2.3.0

Sorry for the trouble here! This is likely due to an error in RdkitGridFeaturizer in the latest DeepChem that we know about and are working on fixing.
