Torch image.load() doesn't work well with named pipes

To reproduce this:

require 'image'
img = image.load('input_pipe')
image.display(img)

On another terminal, run:

mkfifo input_pipe
cat <image_file> > input_pipe

Notice that calling cat <image_file> > input_pipe once doesn't load the image. You have to call it twice. My guess is that image.load opens the file twice. Any help/alternative would be appreciated.

Solution

  • Answered here. Apparently, image.load() opens the image file to find out the file type and then opens it again to call the respective image loader e.g. image.loadJPG()
