Snowflake-connector-python 3.0.4 requires urllib3<1.27,>=1.21.1, but you have urllib3 2.0.4

Deployed with a requirements.txt but get an error message on urllib3 which is incompatible

snowflake-connector-python 3.0.4 requires urllib3<1.27,>=1.21.1, but you have urllib3 2.0.4 which is incompatible. As we can see - I am specifying urlllib3==1.21.1 in the requirements.txt - it seems like the environment is loading 2.04 before the requirements.txt - how to fix?

This is my requirements.txt file

numpy
matplotlib
pandas
urllib3==1.21.1
pyarrow==10.0.1
pillow==9.5
asn1crypto==1.5.1
certifi==2023.5.7

I read the Snowflake python driver documentation carefully and changed my requirements.txt to:

n

umpy
matplotlib
pandas
urllib3==1.26.0
-r https://raw.githubusercontent.com/snowflakedb/snowflake-connector-python/main/tested_requirements/requirements_38.reqs

But now I get an error message:

ERROR: Cannot install urllib3==1.26.0 and urllib3==1.26.16 because these package versions have conflicting dependencies.

(In a previous commit to GH I had specified 1.26.16)

Looks like server-side caching

No, you are actually specifying conflicting requirements. The included requirements file requirements_38.reqs already asks for urllib3==1.26.16 , you don’t need to ask for it again.

You’re right. I took it out - and it sill doesn’t work

The Streamlit docker is already loading urllib3=-2.0.4 or one of the libraries in the snowflake connector is loading urllib3==2.0.4

Here is the requirements.txt now:
numpy
matplotlib
pandas

I have python code that works in streamlit properly It reads from a snowflake table into a dataframe exposes sliders and draws a graph

I copied the file, git committed, pushed and deployed to streatmlit

the same exact python script returns an error ```
snowflake-connector-python 3.0.4 requires urllib3<1.27,>=1.21.1, but you have urllib3 2.0.4 which is incompatible.

This works
https://baseball-metrics-graph.streamlit.app/

Same script does not work
https://baseball-metrics-t2.streamlit.app/

yes but i fixed that and the problem persists.
i even copied a script that works as is and the copied script crashes on this error

This is what seems to be happening in streamlit cloud:

  1. The packages in requirements.txt are installed, including urllib3==1.26.16.
  2. Since streamlit is still missing, it is installed along with its dependencies, without paying any consideration to already installed packages. So the latest urllib3 compatible with streamlit (urllib3==2.0.4) is installed

I was able to fix it by adding streamlit==1.25.0 to requirements.txt.

thx - sounds right if a bit bizarre. will test soon -
