Hi @Charlypocket,

Please add the following line right above uid = 2:

print(user_train_unscaled) # <-- add this line

uid = 2
# form a set ....

then run the code cell again, and share with us everything printed underneath the code cell. After that, please remove the line.

Excellent! Probably printing the message I asked will also lead to rerunning all the cells. However, seeing that message can convince better us to do the rerunning.

Enjoy the rest of the course Charles :wink:

Cheers,
Raymond
