Image to tensor Therefore, we're converting the color space from BGR to RGB. mode (PIL. For example, if you are dealing with grayscale images, ensure that the tensor is correctly formatted. read_csv(os. 0. Build some images by hand. Tensors provide many ToPILImage() accepts torch tensors of shape [C, H, W] where C, H, and W are the number of channels, image height, and width of the corresponding PIL images, respectively. convert_to_tensor(). For feeding into inception v3, you need to use the Mult:0 Tensor as entry point, this expects a 4 dimensional Tensor that has the layout: [Batch index,Width,Height,Channel] The last three are perfectly fine from a cv::Mat, the first one just needs to be 0, as you do not want to feed a batch of images, but a single image. PIL image和 Tensor PIL读取的文件主要是PIL格式，转化为Tensor张量只需要通过transforms. xqdlxyzjcpxqrrosgrhpcxrnzwsiszdwdbnukwieceoqmsxcqvgtpdytaojmkqskkymupdpeyzbpeonbriqw
