Segmentation Violation #8

Closed sam-cts closed 4 years ago

sam-cts commented 4 years ago

I went into segmentation violation while running detection.

then I located it happened in following line:

network_predict_ptr(n, sized.data); in line 17, network.c

I simply switch it to network_predict_image(n, sized); and it works fine

here's the segmentation error that I got before the change

Hello Thanks for the issue. Can your provide hash of used version of AlexeyAB's darknet?

Latest tested by me: 08bc0c9373158da6c42f11b1359ca2c017cef1b5

Currently I am using: 9dc897d2c77d5ef43a6b237b717437375765b527

Seems like breaking changes for us. I'm getting this one

Calloc error - possibly out of CPU RAM

I'll make update soon.

Can you check current version of go-darknet for your environment now? I haven't used _network_predictimage because of internal resizing image (which have done already before object detection), but used _networkpredict (which accepts *net instead &net)
