Hi
I have found an issue closed to support 4-bit quantization although it’s not officially described in the doc 2.

  This issue is created to track fused 4-bit quantization support in Glow.
The fused 4-bit quantization tensor is represented as follows:
| .......





  
  
    
    
  
  


model-compiler seems not to support Int4 quantization.
model-compiler: for the -quantization-precision option: Cannot find option named 'Int4'!

We want to try this quantization mode. It is available in the latest Glow? How can we use that?
