Pytorch tensor 2 list
WebDec 12, 2024 · If each element tensor contain a single value, you can use .item () on it to get this value as a python number and then you can do mean (your_list). If you want to work with Tensors to keep gradients for example. You can use torch.cat (your_list, 0) to concatenate the list into a single tensor. Then you can call .mean () on the resulting tensor. WebMar 13, 2024 · 您好，可以使用以下代码将 OpenCV 读取的数据转换为 Tensor： ```python import torch import cv2 # 读取图片 img = cv2.imread('image.jpg') # 转换为 PyTorch Tensor tensor = torch.from_numpy(img.transpose((2, 0, 1))).float().div(255) ``` 其中，`img.transpose((2, 0, 1))` 将图片的通道维度从最后一维移动到第一维，`float()` 将数据类 …
