ModuleNotFoundError: No module named 'darts'

Question

I followed all the steps described in the Installation procedure of UNIT8, like creating on Python 3.7 ENV on Anaconda and executing pip install u8darts[all].

But this error message keeps popping up on the console screen.

The Code is pretty basic so far:

from darts.models import NBEATSModel

model_PLDHorario = NBEATSModel(input_chunk_length = 48, output_chunk_length = 24)
