到目前为止 Pytorch 模型转 TensorRT 依旧是一件很麻烦的事情,网上许多资料,包括 Pytorch 官网文档在内给出的路径都是 Pytorch 转 onnx 格式,或者转onnx格式前中间先转成 torch script 格式,再用 TensortRT 解析 onnx 格式。 但是这种方式也存在许多问题,例如 Pytorch 转 onnx 之前是否要先转成 torch script ...
再使用numpy对Pytorch得到的结果进行transpose处理(保证和tensorflow输出的结果Tensor格式一致) 对比两者输出的结果是否一致 def conv_test(torch_image, tf_image): """ 测试转换权重后pytorch的卷积层和tensorflow的卷积层输出是否一致 :param torch_image:
However, I am trying to avoid the CPU copy, and create an open3d tensor, then create an open3d image (all on the GPU). It runs but the open3d image is incorrect. I have double-checked and the opencv image from the same torch tensor is fine. ...
最近复现了一篇论文《Learning Continuous Image Representation with Local Implicit Image Function》,具体可参考Aistudio项目《超分辨率模型-LIIF,可放大30多倍》,主要是基于论文代码(torch 1.6)转换而来,特此记录,希望能帮大家避坑。 1. 导入包不同 # Torch Code import torch from torch.utils.data import Dataset...
