What does -1 mean in pytorch view?
Yes, it does behave like -1 in numpy.reshape(), i.e. the actual value for this dimension will be inferred so that the number of elements in the view matches the original number of elements. For instance: import torch x = torch.arange(6) print(x.view(3, -1)) # inferred size will be 2 as 6 / 3 = 2 # …
Get image dimensions with Javascript before image has fully loaded

Swapping the dimensions of a numpy array
The canonical way of doing this in numpy would be to use np.transpose‘s optional permutation argument. In your case, to go from ijkl to klij, the permutation is (2, 3, 0, 1), e.g.: In [16]: a = np.empty((2, 3, 4, 5)) In [17]: b = np.transpose(a, (2, 3, 0, 1)) In [18]: b.shape Out[18]: (4, …
Java/ImageIO getting image dimensions without reading the entire file?
try(ImageInputStream in = ImageIO.createImageInputStream(resourceFile)){ final Iterator<ImageReader> readers = ImageIO.getImageReaders(in); if (readers.hasNext()) { ImageReader reader = readers.next(); try { reader.setInput(in); return new Dimension(reader.getWidth(0), reader.getHeight(0)); } finally { reader.dispose(); } } } Thanks to sfussenegger for the suggestion
