You need to install git-lfs and then pull the repository because the so files are stored using git-lfs. Or download the so file directly manually. ------------------ Original ------------------ From: whw12345...

You need to download it by `mouse click`, not by `wget`.

是由什么错误吗？理论上你配置好了python环境是可以很容易生成的

确实是的，这本身要根据情况进行合理设置

你可以使用pinned memory，也就是cudaMallocHost来分配host的内存，可以优化比较明显

`Scale coefficients must all be positive` occurs when the stored scale value is zero. This is a bug in pytorch_quantization_library. it can be fixed by constraining the value of amax(like,...

also, you can change the scale value using `onnx` in Python.

It would be best if you used the DDP instead of DP.

We used the official pth model in CenterPoint merely. You can find the URL from [here](https://github.com/tianweiy/CenterPoint/blob/master/configs/nusc/README.md).

But openpcdet is a pointpillars-based architecture. This is contradictory to the sparse conv we support. Are you sure you want to train a pointpillars-based model?
