If you happen to look into the TensorFlow source codes, you might find functions that belong to
gen_math_ops which is imported via:
from tensorflow.python.ops import gen_math_ops
gen_math_ops.py does not actually exist in the TensorFlow GitHub repo. This is because
gen_nn_ops.py etc) is generated automatically, thus not included in the repo. But in your local installation, you may find it in
<tensorflow-path> is the path of
tensorflow.__file__. The functions in this automatically generated python code are usually wrappers of the corresponding C++ functions. So if you are interested in understanding how the functions are coded, you won’t find anything useful in here, but must go look at the corresponding C++ functions.
