因为ONNX 本身是支持二维 grid_sample 操作的,而我们并不会使用 ONNX Runtime 运行模型,所以直接导出没有问题,导出后可以使用 Netron 找到 GridSample 节点 当然我们这里捡了一点便宜,如果是 ONNX 完全不支持的算子,就要用点其他手段了。 解决掉 grid_sample 算子的问题之后,可能会遇到另外一个报错: torch.onnx...

当前CNN模型基本都是 float32，将其转换为 INT8 可以降低模型大小，提升速度，精度降低的也不太多。那么在实际中如何实现这个量化了？在网上找到了三种实践方法， 基于腾讯的NCNN， Tensorflow ，Nvidia 的 TensorRT，这里先介绍其中的一种。

A grid sample layer in an INetworkDefinition . This layer uses an input tensor and a grid tensor to produce an interpolated output tensor. The input and grid tensors must shape tensors of rank 4. The only supported SampleMode s are trt.samplemode.CLAMP, trt.samplemode.FILL, and trt.sam...
