A simple test below failed: df = md.DataFrame(mt.random.choice(['a', 'b', 'c'], (100, 2), chunk_size=10))
# Length of 'prefix' (3) did not match the length of the columns being encoded (0)
md.get_dummies(df, prefix=['col1', 'col2']).execute()while it works in pandas: df = pd.DataFrame(np.random.choice(['a', 'b', 'c'], (100, 2)))
pd.get_dummies(df, prefix=['col1', 'col2']) |
