Hi,
After psychopy is run, it will show the interface of the coder, and then it will flash back directly without showing any error information. What’s going on?
Any help will be much appreciated. 
Are you sure there’s no error message in the runner?
Yes, I am sure, and I have also shown it to my teacher, who also believes that there is no problem with my program.
Please could you paste the contents of the log in your runner window and upload your psyexp file and the form excel (if you are using one)
