Loads a PyTorch C++ extension just-in-time (JIT).
To load an extension, a Ninja build file is emitted, which is used
   to compile the given sources into a dynamic library. This library
   is subsequently loaded into the current Python process as a module
   and returned from this function, ready for use.
By default, the directory to which the build file is emitted and
   the resulting library compiled to is
   "/torch_extensions/", where "" is the temporary
   folder on the current platform and "" the name of the
   extension. This location can be overridden in two ways. First, if
   the "TORCH_EXTENSIONS_DIR" environment variable is set, it replaces
