[NakulGoswami]

Hi Abhishek,
In addition,
when I try to run the first code in the book, I get the following error.
I am sure it is somenthing simple, but do please let me know how to proceed?
Is there an updated code list for your book that you can point me to because that would be helpful.

Thanks
Nakul

Hi Abhishek,
I recently bought your book.
I get the following error when I ren the code that is ritten on page 19.

clf.fit(df_train[cols], df_train.quality)
AttributeError: 'list' object has no attribute 'fit'

Can you help with the accurate code?
Thanks
Nakul

Hello Nakul , I fear you have not initialized the model variable clf correctly .
Can u post a pic or snippet of your code ?

To solve this problem, you should to change code to "single_image = pixel_values[1, :].reshape(28, 28)" .It works
