Hi, @HenriKoelewijn @hkoelewijn

I've met this error when run run_test().

What's wrong to me ?

It is caused by the fact that the repository does not include the images. To run it, you need to have a folder ./data/dogscats/train with two folders in there. One for each category of images you want to test. In each of the folders there should be image files. I used google search to get images of dogs and put them in one folder and images of cats in the other. 200 of each should do the trick. This chrome extension can help you download the images: https://chrome.google.com/webstore/detail/bulk-image-downloader/lamfengpphafgjdgacmmnpakdphmjlji?hl=en

Hi, @hkoelewijn , @HenriKoelewijn

Ok, I'll try that.

and will report the result.

Thanks.
