OpenCV issue

[songcui]

Hi,

When I am running on your sample images in Section "Pre-cropped images and training labels for FLIC", I got the following errors:
**
I0511 02:21:53.280088 6621 net.cpp:477] conv2 <- pool1
I0511 02:21:53.280124 6621 net.cpp:433] conv2 -> conv2
OpenCV Error: Assertion failed (scn == 3 || scn == 4) in cvtColor, file /build/buildd/opencv-2.4.8+dfsg1/modules/imgproc/src/color.cpp, line 3648
terminate called after throwing an instance of 'cv::Exception'
what(): /build/buildd/opencv-2.4.8+dfsg1/modules/imgproc/src/color.cpp:3648: error: (-215) scn == 3 || scn == 4 in function cvtColor**

Is it because of a different OpenCV version you are using? What is OpenCV version you are using. Thanks.

It's a bit late now, but anyway:

I always get that error when it doesn't find the images.
Make sure you have a "/" at the end of the "root_img_dir: .." string. And if you're using his flic data, don't put a "train/" or "test/" at the end of that same string, "train/" is part of the image names given in train_shuffle.txt, and it doesn't find the folder "/train/train".

Hi
the parameters is not correct, here is the example, you have to add a / at the end of path
for parameter root_img_dir

 heatmap_data_param {
    source: "/home/ddd/projects/caffe-heatmap/data/flic/train_shuffle.txt"
    root_img_dir: "/home/ddd/projects/caffe-heatmap/data/flic/"
    batchsize: 14
    cropsize: 248
    outsize: 256
