issue when run prepare_test

[gangliu123]

Hi, I got some error when I try to get test.txt by running prepare_test file. Could you give me some help? Thanks a lot.

Exception in thread Thread-1:

Print image file name, ensure file exists. If not, see `Download images and annotations' section in tutorial part-1.
