nn_quantizer.py in the ML-CIFAR10 examples got error KeyError: 'accuracy'

[rafakath2020]

I am executing ML-examples ->cmsisnn-cifar10. While converting trained Caffe model into cmsis-nn by below command

python nn_quantizer.py --model models/cifar10_m7_train_test.prototxt --weights models/cifar10_m7_iter_300000.caffemodel.h5 --save models/cifar10_m7.pkl

getting an error message.

Traceback (most recent call last):
File "nn_quantizer.py", line 614, in
my_model.get_graph_connectivity()
File "nn_quantizer.py", line 231, in get_graph_connectivity
num_branch = len(self.bottom_blob[current_layer])
KeyError: 'accuracy'

Kindly provide any reference for solving the above error.
