converting csv to pickle file

[mahirahaqilah]

Hi , I am really new here, I have this issue where i am not able to convert csv file to pickle file, please correct my code if I am wrong.

Should it be this :
with open('ava_train_v2.csv', 'wb') as f:
pickle.dump(ava_train_v2.csv, f)

or this ?
with open('ava_train_v2.pkl', 'wb') as f:
pickle.dump(ava_train_v2.pkl, f)
