Some method are not implemented

[contactmat85]

HI, I am trying to run your demo, but loadParams from BatchNorm.rs is not implemented. The method is returning a message saying: "fastLoadParams is not implemented". The parsing operation goes ahead but when it is trying to instantiate the network is crashing after conv0 This is the error message that I got: """ 2018-11-02 13:21:16.230 5543-5543/com.rscnn.example I/LayerGraph: layer MobileNet-SSD output:,1,300,300,3 2018-11-02 13:21:16.233 5543-5543/com.rscnn.example I/LayerGraph: layer data output:,1,300,300,3 2018-11-02 13:21:16.248 5543-5543/com.rscnn.example I/LayerGraph: layer conv0 output:,1,150,150,32

It looks to me that is crashing when trying to instantiate the batch normalization layer after conv0.

COuld you clarify please?

Thank you very much

@contactmat85 You should merge the batch norm layers into conv layers， use my merge_bn.py in mobilenet-ssd project to do that.
