import module 'lambda_function': No module named 'pandas' error

Question

I have created a layer in aws for pandas, added this layer into my lambda function. but the code return an error Unable to import module 'lambda_function': No module named 'pandas'. what is the issue for this

My system is windows 11 and I am using python 3.9 and the following commands are used for creating zip file that contains pandas mkdir python cd python pip3 install pandas -t . Compress-Archive -Path . -DestinationPath pandas_layer.zip

Amazon provides AWS SDK for Pandas layers for you, which includes Pandas: aws-sdk-pandas.readthedocs.io/en/stable/layers.html The reason your layer isn't working is because there is a lot more to building a Pandas layer than just doing pip install, you have to include binary linked dependencies, which you can't do easily on a Windows machine. — Mark B

I've built the pandas layer for you. You can download it through this google drive link. This layer is for the x86_64 python3.11 runtime. If you don't trust my code, you can follow the steps here to build it yourself.

Test code:

import json
import pandas

def lambda_handler(event, context):
    # TODO implement
    print(f"pandas: {pandas.__version__}")
    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }

Test result:

Test Event Name
test

Response
{
  "statusCode": 200,
  "body": "\"Hello from Lambda!\""
}

Not only pandas, I can't import any packages using layers.
