Thanks. We are adding those back
bca6cfb

from d2l-en.

So what's the answer to such a problem?

from d2l-en.

@ezzatmostafa96 downgrade d2l to 0.11.0, i.e. pip install d2l==0.11.0 or wait the new patch.

from d2l-en.

To always get the most updated d2l lib (sometimes we may not promptly upload the patch to pypi), simply

git clone https://github.com/d2l-ai/d2l-en.git
cd d2l-en
python setup.py develop

Below lists the uploaded versions of d2l on pypi that you can pip install:
https://pypi.org/project/d2l/#history

For now, you may get the most updated version by

pip install d2l --upgrade

from d2l-en.

@ezzatmostafa96 see my comment above. thanks

from d2l-en.
