#python的用法--》tensor数据类型

#通过transforms.ToTensor来看两个问题

#1. 如何使用transforms(python)

#2. 为何需要Tensor数据类型

img_path = r"F:\PycharmProjects1\DLT\PracticeDataset\train\ants_image\0013035.jpg"

img = Image.open(img_path)

# print(img) #输出img信息<PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=768x512 at 0x18D97553AF0>

#1. 如何使用transforms(python)# tensor_trans=transforms.ToTensor()

# tensor_img=tensor_trans(img)

#上两行等同于tensor_img=transforms.ToTensor()(img)

tensor_img=transforms.ToTensor()(img)

print(tensor_img)
