I suggest the author add “ if __ name __=="__main__" to the code “ #103

Firstly, I am very impressed by the outstanding work you have done.

But I found an issue while using your open source code.

For example, I want to quickly integrate model.py and serialization into my code, but I don't know what the data format input into serialization looks like.

If I were to start processing data from scratch and then run your scripts, it would take a long time.

So I suggest the author write a code under if name=="main" on how to input data

Thanks for this great suggestion. I will try to add more examples of code after this CVPR.

Oh,Thank you. But，PTv3 consumes too much memory. I only use the PTV3 decoder and input tens of thousands of points, but the 24GB graphics card also memory overflow.

Have you enabled FlashAttention? The default setting with a large patch size definitely needs flash attention. But if your local machine cannot install FlashAttention, a smaller patch size like 128 can also work very well.
