Issue with installing easyocr on Cloud Builders Community Firebase image

[Karunanagaraju]

Affected builder image

gcr.io/cloud-builders-community/firebase

Expected Behavior

I expect to be able to install easyocr dependencies using the Cloud Builders Community Firebase builder image.

Actual Behavior

When attempting to install dependencies specified in requirements.txt using python -m pip install -r requirements.txt within a container built from the Cloud Builders Community Firebase builder image, I encounter the following error due to conflicting dependencies. However, the same requirements.txt installs successfully when using a standard Python Docker image.

ERROR: Cannot install -r requirements.txt (line 27) because these package versions have conflicting dependencies.

The conflict is caused by:
easyocr 1.7.1 depends on torch
easyocr 1.7.0 depends on torch
easyocr 1.6.2 depends on torch
easyocr 1.6.1 depends on torch
easyocr 1.6.0 depends on torch
easyocr 1.5.0 depends on torch
easyocr 1.4.2 depends on torch
easyocr 1.4.1 depends on torch
easyocr 1.4 depends on torch
easyocr 1.3.2 depends on torch
easyocr 1.3.1 depends on torch
easyocr 1.3.0.1 depends on torch
easyocr 1.3 depends on torch
easyocr 1.2.5.1 depends on torch
easyocr 1.2.5 depends on torch
easyocr 1.2.4 depends on torch
easyocr 1.2.3 depends on torch
easyocr 1.2.2 depends on torch
easyocr 1.2.1 depends on torch
easyocr 1.2 depends on torch
easyocr 1.1.10 depends on torch
easyocr 1.1.9 depends on torch
easyocr 1.1.8 depends on torch
easyocr 1.1.7 depends on torch
easyocr 1.1.6 depends on torch
easyocr 1.1.5 depends on torch
easyocr 1.1.4 depends on torch
easyocr 1.1.3 depends on torch
easyocr 1.1.2 depends on torch
easyocr 1.1.1 depends on torch
easyocr 1.1 depends on torch
easyocr 1.0 depends on torch

Steps to Reproduce the Problem

1. Use the following configuration in your cloudbuild.yaml file:

steps:

• name: 'gcr.io/project_id/firebase'
  entrypoint: 'bash'
  args:
  - '-c'
  - |
  cd functions
  rm -rf venv
  python -m venv venv
  source venv/bin/activate && python -m pip install -r requirements.txt
  firebase deploy

2. Run the Cloud Build job with the above configuration.

This is related to #669 that updated Node and Alpine versions, since both Node 18 and Alpine 3.18 end of support in early 2025.

The above errors are pointing out that torch an easyocr dependency is not installable. That is due to the fact that Alpine 3.20 has upgraded Python to 3.12 and torch is not supported on Python 3.12 (pythorch#110436) .

You can either pin to an older version of image or build a custom image using python:3.11-alpine3.21 and node 20
