No such option: --device , -d (how to switch between gpu and cpu computing?) #629

Closed TutajITeraz closed 4 months ago

TutajITeraz commented 4 months ago

Hello! I need to switch between gpu and cpu computing, so I read the Usage options (by typing kraken without parameters) and I saw this description:

  -d, --device TEXT               Select device to use (cpu, cuda:0, cuda:1,
                                  ...)  [default: cpu]

I have tried both -d and --device:

$ kraken -i results/8v_mod.jpg results/8v_mod.txt binarize segment -bl ocr -m cremma-generic-1.0.1.mlmodel -d gpu
Error: Invalid value for '-d' / '--text-direction': 'gpu' is not one of 'horizontal-tb', 'vertical-lr', 'vertical-rl'.
kraken -i results/8v_mod.jpg results/8v_mod.txt binarize segment -bl ocr -m cremma-generic-1.0.1.mlmodel --device cpu
Error: No such option: --device

How can i switch between this two? Is help manual wrong?

Im using kraken==5.2.7 installed from pip on Manjaro Linux. (Linux 5.15.160-1-MANJARO)

Hi tutajl. --device must come before the first processing command and the kraken call, so here before binarize. Note that binarization is useless nowadays and will break bl and htr i believe
