title: AWS Lambda, Python, Numpy and others as Layers
body: <p>I have been going at this for a while trying to get python, numpy and pytz added to AWS Lambda as Layers rather than having to zip and throw it at AWS with my .py file. I was able to follow multiple tutorials and all of them failed. </p>
  
  <p>I have resorted to following this guide if I am to go with pandas, numpy or pytz for any functionality (<a href="https://medium.com/@korniichuk/lambda-with-pandas-fd81aa2ff25e" rel="nofollow noreferrer">AWS Lambda with Pandas and NumPy - Ruslan Korniichuk - Medium</a>). So this is good but I do not want to have to recreate a zip each time if things change with my function needs ect. especially as my company is growing. We are simply trying to automate some tasks with Lamba using Cloudwatch to run jobs periodically. Nothing spectacular and I know there may be route with S3 and other instances. However, I have been able to successfully create layers for other libraries except for Pandas, Numpy and Pytz.</p>
  
  <p>So, I am worried about scalability with this method. I am working on a mac and I am not sure what else to do: I have tried using Docker, I have tried building from wheels. Is there any viable tutorials that explain how to do this in detail? </p>
  
  <p>Here are some of the tutorials I have tried. Yes, it does not mean I followed them correctly but I did not succeed in the end with most of them:</p>

  <p>You name it and I might have already went through the steps, especially in these articles, to complete this task. And a lot of Stack question comments as well, which have been very helpful and insightful.</p>
  
  <p>Thanks in advance for any advice, just here to learn! </p>
