DNN (SqueezeNet) OpenCV Error: Assertion failed in cv::Mat::reshape
Hi,
Am trying to deploy a trained Caffe model from DIGITS with OpenCV 3.1.0. I have attempted the sample code on both LeNet and AlexNet models without any problem.
However, for benchmarking purpose, I tried do run SqueezeNet V1.1 on the same sample code but having an error at the getMaxClass() function where the OpenCV reshape function is called.
The full error message:
OpenCV Error: Assertion failed (dims <= 2) in cv::Mat::reshape, file C:\opencv\sources\modules\core\src\matrix.cpp, line 982
Kindly advise on possible solutions.
For your reference, the full code I am running SqueezeNet on is as follows:

can it be, that this simply does not have a "softmax" layer ?
Thanks for the reply. Sorry for forgetting that I have actually made some small changes to the final layers, as follows:
which essentially replaces "accuracy_top5" with "softmax" and includes, exclude { stage: "deploy" }, include { stage: "val" } and include { stage: "deploy" } to the resp. layers. Managed to get a trained model.
Did you figure it out yet?
