Problem converting mxnet model to keras

[mkhoshle]

Platform (like ubuntu 16.04/win10): macOS Catalina V10.15.6

Python version: 3.8 Source framework with version (like Tensorflow 1.4.1 with GPU): mxnet1.6.0 Destination framework with version (like CNTK 2.3 with GPU): Keras '2.4.3' Pre-trained model path (webpath or webdisk path): https://www.dropbox.com/s/tj96fsm6t6rq8ye/model-r100-arcface-ms1m-refine-v2.zip?dl=0

Running scripts:

1. python3 -m mmdnn.conversion._script.convertToIR -f mxnet -n pretrained_model/model-r100-ii/model-symbol.json -w pretrained_model/model-r100-ii/model-0000.params -d . --inputShape 3,112,112

2. python3 -m mmdnn.conversion._script.IRToCode -f keras --IRModelPath ArcModel.pb --dstModelPath converted_ArcModel.py --IRWeightPath ArcModel.npy

3. python3 -m mmdnn.conversion.examples.keras.imagenet_test -n converted_ArcModel.py -w ArcModel.npy --dump mxnet_ArcModel.h5

When I run the third command I get the following error, could anyone help me with this error, please?
