title: Large Categorical Value in Pandas
body: <p>i want to convert my categorical value into one hot encoding/get_dummies but i am having 4340 unique categorical value. I am getting memory error because of this. How can i handle this type of large categorical values.</p>
  
  <p><strong>Update:</strong></p>
  
  <p>Since the data is sensitive so i can not post all the data i am giving the column name something different but the values are like that and since it is not possible to post all 4340 unique categorical values i am giving small sample.</p>
