What did you do?

Using a docker container to create a lambda layer for a function. Our current function is in 3.8 and going to be deprecated soon. Would be nice to be able to update it to the latest python version. We can move to 3.9 but would like to use some features in 3.11/3.12

What did you expect to see?

Layer usage but instead get the following error
cannot import name 'Mapping' from 'collections'

Can you set logging to DEBUG and collect the logs?

import logging
import os

for logger_name in ('snowflake.connector',):
    logger = logging.getLogger(logger_name)
    logger.setLevel(logging.DEBUG)
    ch = logging.StreamHandler()
    ch.setLevel(logging.DEBUG)
    ch.setFormatter(logging.Formatter('%(asctime)s - %(threadName)s %(filename)s:%(lineno)d - %(funcName)s() - %(levelname)s - %(message)s'))
    logger.addHandler(ch)

@IRISDavidD snowpark supports 3.11. Could you try it?

[IRISDavidD]

I tried 3.11 and get the following issue running:

pip3 install --target=. --platform manylinux2010_x86_64 --only-binary=:all: -r requirements.txt
also tried standard pip3 install

ERROR: Cannot install -r requirements.txt (line 1) because these package versions have conflicting dependencies.

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

[sfc-gh-yixie]

what's in your requirements.txt?

[IRISDavidD]

snowflake-connector-python

just to get this working

[sfc-gh-yixie]

A very old version (1.x) of python connector was being installed then an error was raised. The latest version is 3.6.0.
Do you know why such an old version was being installed?

[IRISDavidD]

No idea I thought that was the case but was strange - I will try again and define the latest version

removed --platform manylinux2010_x86_64 and installs but this doesn't work in the lambda layer I get this error "Unable to import module 'lambda_function': /lib64/libc.so.6: version `GLIBC_2.28' not found (required by /opt/python/cryptography/hazmat/bindings/_rust.abi3.so)"

[sfc-gh-yixie]

I haven't tried the lambda myself. Does this help? https://interworks.com/blog/2023/03/28/how-to-install-the-snowflake-python-connector-in-aws-lambda/

[IRISDavidD]

I have 3.9 is working was hoping for a more updated python version.

I'm having the same issue with python 3.11

[FreyGeospatial]

Even with 3.9, I get "Unable to import module 'lambda_function': /lib64/libc.so.6: version `GLIBC_2.28' not found (required by /opt/python/cryptography/hazmat/bindings/_rust.abi3.so)"

[FreyGeospatial]

I have 3.9 is working was hoping for a more updated python version.

@IRISDavidD How did you get this working in 3.9?

[IRISDavidD]

Reply no I haven't - still on 3.9 and upgrading all our snowflake lambdas to 3.9 from 3.8 before the depreciation date

[FreyGeospatial]

I haven't tried the lambda myself. Does this help? https://interworks.com/blog/2023/03/28/how-to-install-the-snowflake-python-connector-in-aws-lambda/

@sfc-gh-yixie unfortunately this does not work for me.

[sfc-gh-aling]

hey @IRISDavidD @FreyGeospatial , are you still observing the issue?

I would recommend you to try, inside your docker image, using Python >= 3.8 and only pip installing the latest connector first to see if connector alone works, and then we can gradually add back other dependencies back to see which are conflicts and how to resolve them.
