[Solved] Problem with tabular_learner.predict() on a single row

Solved. Input to predict(row) must be processed, numeric data, not the raw, alpha-numeric data in df_final_nn above.

Thus learn.predict(learn.dls.train.all_cols.iloc[0]) works, coz’ the fields are all numeric:

YearMade                 1.000000
Coupler_System           0.000000

p.s. learn.predict(learn.dls.train.iloc[0]) doesn’t work, coz’ it’s a TabularPandas, not a panda.series.Series
