In colab, I trained a model and it works well
from google.colab import drive
drive.mount('/content/gdrive')
!pip install fastai --upgrade
from fastai.tabular.all import *
from fastai import __version__
print(__version__)
learn = load_learner(fname='/content/gdrive/My Drive/mymodel',cpu=False)
learn
Mounted at /content/gdrive
Collecting fastai
Successfully installed fastai-2.4 fastcore-1.3.20
2.4
<fastai.tabular.learner.TabularLearner at 0x7f87523a1ed0>
However, I failed in loading it in Windows:
Python 3.8.5 (default, Sep 3 2020, 21:29:08) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from fastai import __version__
>>> __version__
'2.4'
>>> from fastai.learner import *
>>> load_learner(fname='./mymodel')

What did I miss?
