nswamy opened a new issue #11901: CPP_Package Lenet Example needs rework to improve the accuracy URL: https://github.com/apache/incubator-mxnet/issues/11901 ## Description Running Current CPP_Package Lenet Example shows the accuracy is not improving. The network architecture needs to be revisited to improve the accuracy. Logging/Documentation/etc., needs to be improved as well for all the CPP Package Examples. ``` [08:03:11] lenet.cpp:191: Epoch [251] Time cost :2.82437, accuracy: 0.0917187 [08:03:14] lenet.cpp:191:
