Arguments

Arguments:

• 1: disabled
• 0: enabled

Default: 0

Restrictions: If the network model is large and the memory overcommitment function is disabled, the memory may be insufficient during model tuning. As a result, the model tuning fails.

Suggestions and Benefits

None

Examples

--disable_reuse_memory=0

Dependencies and Restrictions

Selects the operator to skip in memory overcommitment. (Memory overcommitment is enabled by default.) The operator (or operators separated by commas) specified by OP_NO_REUSE_MEM will use exclusively allocated memory. For details, see Environment Variables.

• Configuration by node name:
  After the node name is converted to be compatible with the CANN platform, ensure that the node name is correctly configured. You can obtain the node name by setting DUMP_GE_GRAPH and viewing the name field in the exported ge_onnx_xxx_Build.pbtxt graph.
