why is he using

embed_out[ix][ij]=embedding_dict[a[ix][ij].lower()]
it should be
embed_out[ix][ij]=embedding_dict[a[ij].lower()]
check the below screenshot

hey @Par1hsharma ,
the format might have changed.

Can you share me your complete code , so that i can check it.

Note : just don’t depend upon the video, the format of those API’s might change in time , hence accordingly you also might need to change your code.

Please explain this part

it is just the difference between the ways the input embedding were provided.
At the when the video was recorded the embeddings seems to be different , now they are different , hence that code problems .
You can ignore that and move according to your solution.
