QProcess successfully launched .py file but can only do few python functions, but if i run .py in pycharm or cmd,everything works well


This Content is from Stack Overflow. Question asked by Yuesheng Ke

i have a .py file like this:

print("yt_train_log: executing AUO.py")
work_dir = os.path.abspath(os.path.dirname(__file__))
configPath = work_dir + "/train.ini"
config = configparser.ConfigParser()
print("yt_train_log: configPath: {}".format(configPath))
savedStdout = sys.stdout  
sys.stdout = open('out.txt', 'w+') 
sys.stdout = savedStdout 

this python file can well work in pycharm 、 cmd or notebook,but when i use QProcess to excute this .py, it failed. After i delete the last 3 lines from the .py file, it can work well in QProcess. i tryed give admin rights to the .py file and .exe and retry in QProcess, it still failed.
