 Building TensorFlow C++ API is very tricky and can be a pain as there is not much information you can find about it even on TensorFlow's official documentation. Following you will find a step-by-step instruction showing how to build TensorFlow C++ v2 on Linux. It works well for my Ubuntu 20.04 running on AMD Ryzen processors.

 ## Dependencies
 
 - Conda
-- Python
+- Python + NumPy
 - GCC 5 or higher
 - Bazel*
 - Protobuf*
 
 *a supported version depends on the version of TensorFlow. For TensorFlow v2.7, Python 3.9.9, GCC 10.3.0, Bazel 3.7.2, and Protobuf 3.9.2 work for me.
