Keras module not found in old notebook

I imported this old notebook I had for analyzing sales data and I downloaded anaconda navigator on a pc. Im getting this keras module not found error:

ModuleNotFoundError                       Traceback (most recent call last)
Input In [1], in <cell line: 7>()
      5 from import rmse
      6 from sklearn.preprocessing import MinMaxScaler
----> 7 from keras.preprocessing.sequence import TimeseriesGenerator
      8 from keras.models import Sequential
      9 from keras.layers import Dense

ModuleNotFoundError: No module named 'keras'

How do i fix this?

i was able to download the keras module in the anaconda navigator. Then I got the message for tensorflow and i tried downloading it but its been downloading for quite a while now. Is it so big that it takes such a long time?

yes, tensorflow is quite large! Do you have everything working now as you would like?
