How to import the numpy module on AWS lambda?

Question

I am new beginner for AWS system, I am doing my python project, want to use AWS lambda function to run my serverless python program, I have all my resource on AWS S3 bucket, I would like to simply take one of my images from S3 bucket (let's say source-bucket), turn it to grey color and save it back to the other S3 bucket (result-bucket). My question is how to I import the numpy and the cv2 module on AWS lambda, I followed guide from https://serverless.com/blog/serverless-python-packaging/ however, it return me an error message:

An error occurred: NumpyLambdaFunction - Function not found:
arn:aws:lambda:us-east-1:......:function:numpy-test-dev-numpy (Service:
AWSLambdaInternal; Status Code: 404; Error code: ResourceNotFoundException;
Request ID: ....).

What can I do to fix this error? or is there another better method for doing so? (P.S. I am using the window computer) Thank you very much!
