PIL python library loads only 0 but still displays image

Question

import numpy as np
from PIL import  Image


image_path = f"D:datasetsdataset_game_objects\1.jpg"
image = Image.open(image_path)
image_array = np.array(image)
image.show()

I am running following simple code for testing if path to my image is correct but I have encouter rather weird error my image opens but when I transform it into array i get following output

[[[0 4 0]
  [0 4 0]
  [0 4 0]
  ...
  [0 0 0]
  [1 0 0]
  [1 0 0]]
 [[0 4 0]
  [0 4 0]
  [0 4 0]
  ...
  [0 0 0]
  [1 0 0]
  [1 0 0]]
 [[1 3 0]
  [1 3 0]
  [1 3 0]
  ...
  [0 0 0]
  [1 0 0]
  [1 0 0]]
 ...
 [[0 0 0]
  [0 0 0]
  [0 0 0]
  ...
  [2 1 0]
  [3 2 0]
  [4 3 1]]
 [[0 0 0]
  [0 0 0]
  [0 0 0]
  ...
  [1 0 0]
  [1 0 0]
  [2 1 0]]
 [[0 0 0]
  [0 0 0]
  [0 0 0]
  ...
  [1 0 0]
  [1 0 0]
  [1 0 0]]]

so I tried PilToTensor() as transformation

tensor([[[0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         ...,
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.]],

        [[0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         ...,
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.]],

        [[0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         ...,
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.],
         [0., 0., 0.,  ..., 0., 0., 0.]]])

So this is rather weird behavior the the pictures are all jpgs

Answer 1

Have you already taken into account that torchvision.transforms.PILToTensor method changes dimensionality oder. Quoting from the documentation:

Converts a PIL Image (H x W x C) to a Tensor of shape (C x H x W).

Ref: https://pytorch.org/vision/stable/generated/torchvision.transforms.PILToTensor.html

If yes , could you please share the pic as well, I can give it a go.

P.S: Could’ve simply commented this but don’t have enough points in my profile to do that yet

I just needed to change my transformation function
