Install TVM on Apple M1 Pro

Questions
#1

I want to install TVM on Apple M1 Pro, but some errors occur while building.

Here are my installing step:

  1. Download and install anaconda for Apple-M1.
  2. Modify python=3.7 and execute conda env create --file conda/build-environment.yaml
  3. Set LLVM ON at config.cmake 
conda install ninja
cmake .. -G Ninja -DCMAKE_OSX_ARCHITECTURES=arm64
ninja -j8
sudo ninja install

conda build --output-folder=conda/pkg  conda/recipe

And error occurd:

No numpy version specified in conda_build_config.yaml.  Falling back to default numpy value of 1.16
WARNING:conda_build.metadata:No numpy version specified in conda_build_config.yaml.  Falling back to default numpy value of 1.16
