sklearn and pandas in AWS Lambda

Question

I made a front end where I would like to make REST calls to an AWS Lambda interfaced with AWS API Gateway.

I dumped my model as a pickle file (and so my encoders) which I initially trained locally. I then stored these files in a S3 bucket.

The problem is that I cannot import libraries such as pandas and sklearn to make model predictions because the lambda console is unable to find them.

Does anyone have any suggestions to help solve this issue?
