Using Keras and cv_bridge in ROS melodic

Hello,

I am working on a project that involves using Keras to develop a model for detecting traffic signs through a raspberry pi camera. If I run my code in an anaconda environment, I can use Keras and load in the model, but I run into the following error: ImportError: dynamic module does not define module export function (PyInit_cv_bridge_boost).

I then tried to run my code using python2 as opposed to just python. The cv_bridge function works as needed but then I can not load in the Keras model since I believe Keras only works in python 3.

Any help would be greatly appreciated, thanks for your time.

Hello,

I experienced recently the same issue with ROS Kinetic, I ended up understanding that Python 3 wasn't having all the required packages to run Cv_Bridge smoothly, since Cv_Bridge builds for Python 2.7. Also ROS is based on Python 2 which is already deprecated since Jan 1st, 2020.

All I had to do was to install the missing dependencies for python3 and build Cv_Bridge from the official vison_opencv repository. (Please refer to this Stackoverflow answer for detailed instructions) .

And for Keras, you need to have at least Tensorflow 2.2.0 installed, which itself needs python 3 to work properly on your machine. You can work around with Tensorflow 2.1.0 that is supported by python 2.7, but you will be restricted on resources and implementation solutions.

Cheers!
