6.3. PTQ Conversion Steps

Based on the above description of the PTQ conversion principle and process, we can be informed that the the complete development process of the model with the D-Robotics toolchain needs to go through five important phases: Floating-point Model Preparation, Model Checking, Model Conversion, Performance Evaluation, and Accuracy Evaluation. This section describes the overall steps of PTQ conversion.

• 6.3.1. Floating-point Model Preparation
• 6.3.2. Model Checking
  • 6.3.2.1. Use the hb_mapper checker Command to Check Your Model
  • 6.3.2.2. Exception Handling
  • 6.3.2.3. Interpret Model Check Results
  • 6.3.2.4. A Guide to Optimize the Check Results
• 6.3.3. Prepare Calibration Data
• 6.3.4. Model Quantization and Compilation
  • 6.3.4.1. Convert the Model Using the hb_mapper makertbin Command
  • 6.3.4.2. Model Conversion Interpretation
  • 6.3.4.3. Interpret Conversion Results
  • 6.3.4.4. Interpret Conversion Output
• 6.3.5. Model Performance Analysis
  • 6.3.5.1. Use the hb_perf Tool to Evaluate Model Performance
  • 6.3.5.2. Evaluate Actual Model Performance on Dev Board
• 6.3.6. Model Accuracy Analysis
