Hi,
According to this 1, I have set Torch_DIR to /python3.7/site-packages/torch/share/cmake/Torch which contains TorchConfig.cmake  TorchConfigVersion.cmake.
But when I run cmake to /env/lib/python3.7/site-packages/torch/include/torch/csrc/api/include/torch, I get the error:
CMake Error at CMakeLists.txt:4 (find_package):
  By not providing "FindTorch.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Torch", but
  CMake did not find one.

  Could not find a package configuration file provided by "Torch" with any of
  the following names:

    TorchConfig.cmake
    torch-config.cmake

  Add the installation prefix of "Torch" to CMAKE_PREFIX_PATH or set
  "Torch_DIR" to a directory containing one of the above files.  If "Torch"
  provides a separate development package or SDK, be sure it has been
  installed.
