Segmentation fault when runnning inference with pre trained weights

[LucasMahieu]

I am trying to run the inference.py script with the pre trained weights.

here is my main :

if __name__ == '__main__':
    infer = Inference(config_file = 'HG/config.cfg', model = 'HG/hg_refined_200', yoloModel = 'HG/YOLO_small.ckpt')
    infer.webcamSingle()

But I am facing a segfault :

Does someone have any idea ?
