Compatibility Issue with tflite-runtime Version for pycoral Installation

[aletes67]

Description

Hello,

I am encountering an issue while trying to install pycoral with tflite-runtime. The pycoral package seems to require tflite-runtime==2.5.0.post1, but this specific version is not available. The available versions of tflite-runtime are 2.13.0 and 2.14.0.

Here is the error message I receive during the installation:

ERROR: Could not find a version that satisfies the requirement tflite-runtime==2.5.0.post1 (from pycoral) (from versions: 2.13.0, 2.14.0)
ERROR: No matching distribution found for tflite-runtime==2.5.0.post1

Steps to Reproduce:

1. Create and activate a virtual environment:

   python3 -m venv myenv
   source myenv/bin/activate

2. Attempt to install pycoral:

   pip install git+https://github.com/google-coral/pycoral

Environment:

• OS: Ubuntu 22.04
• Python Version: 3.10.12
• tflite-runtime Available Versions: 2.13.0, 2.14.0

Expected Behavior:
pycoral should install without errors using a compatible version of tflite-runtime.

Actual Behavior:
The installation fails due to the unavailability of tflite-runtime==2.5.0.post1.

Temporary Workaround:
I have attempted to install tflite-runtime==2.14.0 and then install pycoral with the --no-deps flag, but this results in a ModuleNotFoundError for pycoral.pybind.

Error Log:

ModuleNotFoundError: No module named 'pycoral.pybind'

Could you please provide guidance on how to resolve this issue? Is there a recommended version of tflite-runtime that is compatible with pycoral, or is there a way to update the dependencies to support the available versions of tflite-runtime?

Thank you for your assistance.
