Good Day!
Hi, i have a problem in line #52 of traffic_prediction.py. Please, you can help me to resolve this error?

test_datapoint_encoded[i] = int(label_encoder[count].transform(test_datapoint[i]))
File "C:\Python35\lib\site-packages\sklearn\preprocessing\label.py", line 128, in transform
y = column_or_1d(y, warn=True)
File "C:\Python35\lib\site-packages\sklearn\utils\validation.py", line 614, in column_or_1d
raise ValueError("bad input shape {0}".format(shape))
ValueError: bad input shape ()

Best Regards!

Solution:
Change the line to:
test_datapoint_encoded[i] = int(label_encoder[i].transform([test_datapoint[i]]))
