[Wait for #2615][Layer] Enable mixed precision - pooling2d_layer #2613
Conversation
We will add Var32 Tensor if the Variable Weight is not Full precision (FP32). This eables the Weight Update with full precision and only Apply Gradient Process ueses this Tensor. Therefore, the lifespan of this tensor should be "ApplyGradient". . Modify TensorPool to generate Weigth considering Mixed Precsion. **Self evaluation:** 1. Build test: [X]Passed [ ]Failed [ ]Skipped 2. Run test: [X]Passed [ ]Failed [ ]Skipped Signed-off-by: jijoong.moon <[email protected]>
This pr create the variable fp32 tensor when we create the Weight and Optimizer Weight. . update the manager to create Weight with var32 tensor which requested to weight pool. . update the weight requests with Weight Spec and var, grad and var32 tensors which created already. . add clone Tensor with specific type in tensor.h Resolves: **Self evaluation:** 1.

This commit modify apply gradient in optimizer. We do not need to save optimizer variables in weight type. Only Optimizer needs the optimizer variables and we should update the weight with full precision to maintain the accuracy. Therefore, remove the var32 tensors for optimizer variables.

This PR enables the Mixed Precision Training. For now only FP16-FP32 is considered. Additional Test cases will be added. . add getSortedLayerIdx to set the graph order for fowarding. . change clip_weights to lazy_apply_weights to use both cases. . add fowarding_op to run forwarding from that layer which has a gradient with nan. . add while loop for re-run backwarding after reset the loss scale. . add setLossScale in RunLayerContext . add check the gradient if mixed precsion enable. **Self evaluation:** 1.

This PR add Execution Mode parameter when we compile. The default is ml::train::ExeuctionMode::TRAIN. Currently we do not support compiler optimization for inference mode such as batch normalization fusing, etc. But we will add more optimization depending on the exeuction mode.

This PR includes Mixed Precision support for batch normalization layer. When the training, BN layer should run full precsion with FP16 Weight data. Therefore, Reading the FP16 data read and data coversion of the current Weight and Activation are required. For the Inference, we do need compiler optimization like bn fusing. So it also includes execution mode parameters for compile. Because of compilcate data conversion of bn layer, test case generation also needs to update, so that taking the fp16 input,output tensors and weights and converting FP32 weight for computation. For veification, we do need convert FP32 to FP16. **Self evaluation:** 1. Build test: [X]Passed [ ]Failed [ ]Skipped 2.
