When I run
opt_fn = partial(optim.Adam, betas=(0.8, 0.99)) in the imdb.ipynb notebook here: https://github.com/fastai/fastai/blob/master/courses/dl2/imdb.ipynb. I am getting the above error. I am not able to know which module partial belongs to so that I can import it.
Also, can someone tell me where I can get all the imports required for the imdb.ipynb notebook above
