I have looked into the cffi extensions but it seems all the examples are based on c code examples.
I am working with the message_filters class in ROSCPP to exchange image from different sensors on a robot. I will like to process the sensor images with pytorch. rospy would not help given its non-support for the message_filters class. Besides, the little support that was added in python is very slow. It seems my best bet is to write a cffi extension and import my class into pytorch.
Are there any examples of exporting c++ classes with cffi extension in pytorch? Would appreciate any pointers on this. Thanks!
