- ndarray --> PILimage
- PILimage --> ndarray
- Tensor --> ndarray
- ndarray --> Tensor
- ndarray数据转换数据类型
- ndarray --> List
- List --> Tensor
From PIL import Image y = Image.fromarray(array)
PILimage --> ndarray
From PIL import Image image = Image.open(“…..”) img = np.asarray(image)
Tensor --> ndarray
import numpy as np yy = np.array(tensor)
ndarray --> Tensor
tensor = torch.from_numpy(ndarray)
tip：返回的张量和ndarray共享同一内存。对张量的修改将反映在ndarray中，反之亦然。
ndarray数据转换数据类型
array.astype(np.uint8)
将array复制，并将数据类型强制转化为int8
ndarray --> List
import numpy as np n = np.array([[1,2],[3,4],[5,6]]) m = n.tolist()
List --> Tensor
tensor = torch.tensor(list)
