title: How to import the numpy module on AWS lambda?
body: <p>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 <a href="https://serverless.com/blog/serverless-python-packaging/" rel="nofollow noreferrer">https://serverless.com/blog/serverless-python-packaging/</a> 
  however, it return me an error message:</p>
  
  <pre class="lang-none prettyprint-override"><code>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: ....).
  </code></pre>
  
  <p>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!</p>
