Seeh here this helped me: https://stackoverflow.com/a/47889702/490647

first install the package pip installl win_unicode_console

then add into your code

import win_unicode_console
win_unicode_console.enable()

@simonfranz thank you but it doesn't work :(

i open my cmd then

python
import win_unicode_console
win_unicode_console.enable()

after that, i use this command to train my model:

flow --model new_model_guinea_pig/tiny-yolo-voc-1c.cfg --load new_model_guinea_pig/tiny-yolo-voc.weights --train --annotation new_model_guinea_pig/xml_gp/ --dataset new_model_guinea_pig/guinea_pig/ --gpu 0.0 --epoch 10

but it returns this:

File "<stdin>", line 1
    flow --model new_model_guinea_pig/tiny-yolo-voc-1c.cfg --load new_model_guinea_pig/tiny-yolo-voc.weights --train --annotation new_model_guinea_pig/xml_gp/ --dataset new_model_guinea_pig/guinea_pig/ --gpu 0.0 --epoch 10
