load_url_image

deepinv.utils.load_url_image(url=None, img_size=None, grayscale=False, resize_mode='crop', device='cpu', dtype=torch.float32)

Load an image from a URL and return a torch.Tensor.

Parameters:

• url (str) – URL of the image file.

• img_size (int, tuple[int]) – Size of the image to return.

• grayscale (bool) – Whether to convert the image to grayscale.

• resize_mode (str) – If img_size is not None, options are "crop" or "resize".

• device (str) – Device on which to load the image (gpu or cpu).

Returns:

torch.Tensor containing the image.
