questions about interactive reviewer #12

Closed cv-lab-x closed 5 months ago

hi, thanks for your great work, how to do interactive review with your compressed model? @Kevin-2017 Looking forward to your reply, thanks!

Hi thank you for your intreast! Regarding your query about interactive review with the compressed model, it's important to note that the model, after quantization, is not directly compatible with interactive review. However, there are alternative ways to achieve this:

  1. Alternative Method with dequantize(): In the ./vectree/vectree.py directory, there is a dequantize() function. You can use this function to load the compressed model. After loading, the funciton save the model to a PLY file, which is compatible with iterative viewers.

  2. Using render.py: You can view the model through render.py. This method should allow you to visualize the model effectively.

I noticed the currently uploaded render.py does not directly support the model after Vectree quntization, I would update that part by Friday.

You could render the quantized model with python render_video.py --load_vq now :D
