Answer 1

The Val columns will probably not have a numerical dtype for some reason, and all non-numerical (eg object dtype) columns are removed in resample.

To check, just look at df.info().
To convert it to a numerical columns, you can use astype(float) or the convert_objects (pd.to_numeric starting from v0.17).
