Tuning Workflow

Supported TensorFlow versions include 1.15 and 2.6.5.
This commissioning entry supports the following models:
- Atlas training products
- Atlas A2 training products/Atlas A2 inference products
- Atlas A3 training products/Atlas A3 inference products

There are two types of tuning in the training scenario:

Subgraph and operator tuning: Figure 1 shows the tuning procedure. For detailed operations, see Table 1.
Gradient tuning: Figure 2 shows the tuning procedure. For detailed operations, see Table 2.
