Hi,
I’m trying to finetune an SSD model to detect a certain object in a custom dataset.
I downloaded the images, created the .lst files, and the corresponding train.rec and test.rec files following the tutorial. I first used a slightly modified version of finetune_detection.py and everything works ok, but this way the accuracy on the validation set is not provided.
I would like to track it in order to decide when to stop the training, and I seem to understand that the validation accuracy is calculated when using the full train_ssd.py script.
However, I’m having trouble figuring out how to set the right arguments to run it on my custom dataset.
I tried something in the line of:
python train_ssd.py --data-shape=512 --dataset-root=custom_dataset_path/ --epochs=10
but I’m getting the error:
OSError: ~/.mxnet/datasets/voc is not a valid dir. Did you forget to initialize datasets described in [...]
Any suggestions? Thanks!
