1. How to package and release python together with dependencies and build tools for python?

---

1. If we check the Python library, we will find that this should be the same as the wrapper file. Check the official website of tensorflow and python and some problem-solving websites, we will know: when the pywrap_tensorflow_internal.py module is imported, the dynamic link _pywrap_tensorflow_internal.so will be loaded

2. How did this file come from? It turns out that when tensorflow is compiled with bazel, swig will generate two wrapper files: pywrap_tensorflow_internal.py and pywrap_tensorflow_internal.cc, the former is to connect to the upper layer Python calls, and the latter to the lower layer C API calls

3. What is swig? The front-end multi-language implementation requires a swig wrapper. The good thing about tensorflow is that it provides such a multi-language front-end interface. SWIG encapsulates c/c++ into a python-callable SO text dynamic link library, so that we can complete deep learning model training and testing in other languages
