Scroll up this thread and the other poster was asking if you can use pytorch and tensorflow from C. Both are C++ libraries, so accessing them from C/C++ is pretty trivial and has first-class support.

You should read more carefully before responding.

I said "beside Python, and C/C++ in which they are written"

You: "you can see people are using it from C".

What a surprise that library usable from Python through wrapped C API has C API!
