 ## An overview of the architecture
 
 The overall principle of the model compression tool is briefly introduced here to help you understand the workflow.
-**figure 1** shows the architecture of the model compression tool, which is a API-relying relation from top to bottom. The distillation, quantization and pruning modules all rely on the bottom paddle framework indirectly. At present, the model compression tool serves as a part of PaddlePaddle framework, so users who have installed paddle of ordinary version have to download and install paddle supporting model compression again for the compression function.
