Cannot show progress bar when using pytest in pycharm

[jiahao-shen]

When i run the following code with pytest in pycharm, the progress bar didn't show in real time.

from tqdm import trange
from time import sleep


def test_1():
    for _ in trange(100):
        sleep(0.03)

It showed after finished running, like this.

But if i run the code like this, the progress bar shows.

from tqdm import trange
from time import sleep
import logging

logging.basicConfig(level=logging.DEBUG)


def test_1():
    for _ in trange(100):
        logging.debug('')
        sleep(0.03)

I really don't know how to fix it.

interesting - seems flush() is ignored and flushing only occurs when \n is printed. Seems to be an upstream PyCharm issue
