Table 1. Generated File Information
Name TensorFlow Compatible Usage Description
quantize_train_graph.pb Yes Train The quantize train graph.
quantize_eval_graph_{suffix}.pb Yes Evaluation with checkpoint The quantize evaluation graph with quantize information frozen inside. There are weights in this file and it should be used together with the checkpoint file in evaluation.
quantize_eval_model_{suffix}.pb Yes
  • 1: Evaluation
  • 2: Dump
  • 3: Input to VAI compiler (DPUCAHX8H)
The frozen quantize evaluation graph, weights in the checkpoint, and quantize information are frozen inside. It can be used to evaluate the quantized model on the host or to dump the outputs of each layer for cross check with DPU outputs. The XIR compiler uses it as an input.

The suffix contains the iteration information from the checkpoint file and the date information. For example, if the checkpoint file is "model.ckpt-2000.*" and the date is 20200611, then the suffix is "2000_20200611000000."
