Look n_classes ,your dataset have same n_classes? or Look https://github.com/freekoy/comic-textboxs/blob/master/ssd7_evaluation_comic.ipynb
I have the same problem, have you solved yet?

I meet the same problem, my solution is as follows:
model = load_model('ssd300.h5')
m_input = model.input
m_output = model.output
decoded_predictions = DecodeDetections(confidence_thresh=0.5,
iou_threshold=0.45,
top_k=200,
nms_max_output_size=400,
coords='centroids',
normalize_coords=True,
img_height=300,
img_width=300,
name='decoded_predictions')(m_output)
model = Model(inputs=m_input, outputs=decoded_predictions)
As you see, if you build model using load_model
method, in fact the model is saved in training
mode, you should set the model to inference
mode by adding DecodeDetections
layer at the end of the original model.
Hope it helps you!
I am trying to train and evaluate the ssd7 on my own datasets,using the code adapt from the ssd300 evaluation code, but i got this error : Producing predictions batch-wise: 100%|██████████| 9/9 [00:17<00:00, 1.91s/it] Matching predictions to ground truth, class 1/5.: 0%| | 0/11 [00:00<?, ?it/s]Traceback (most recent call last): File "C:/Users/lenvov/PycharmProjects/lyk/DIY_robot/ssd_keras/ssd7_evaluate.py", line 196, in
