Test a model

NAS

To test nas method, you can use following command

python tools/${task}/test_${task}.py ${CONFIG_FILE} ${CHECKPOINT_PATH} --cfg-options algorithm.mutable_cfg=${MUTABLE_CFG_PATH} [optional arguments]

• MUTABLE_CFG_PATH: Path of mutable_cfg. mutable_cfg represents config for mutable of the subnet searched out, used to specify different subnets for testing. An example for mutable_cfg can be found here.

The usage of optional arguments are the same as corresponding tasks like mmclassification, mmdetection and mmsegmentation.

Pruning

Split Checkpoint(Optional)

If you train a slimmable model during retrain, checkpoints of different subnets are actually fused in only one checkpoint. You can split this checkpoint to multiple independent checkpoints by using following command

python tools/model_converters/split_checkpoint.py ${CONFIG_FILE} ${CHECKPOINT_PATH} --channel-cfgs ${CHANNEL_CFG_PATH} [optional arguments]

• CHANNEL_CFG_PATH: A list of paths of channel_cfg. For example, when you retrain a slimmable model, your command will be like --cfg-options algorithm.channel_cfg=cfg1,cfg2,cfg3. And your command here should be --channel-cfgs cfg1 cfg2 cfg3. The order of them should be the same.

Test

To test pruning method, you can use following command

python tools/${task}/test_${task}.py ${CONFIG_FILE} ${CHECKPOINT_PATH} --cfg-options algorithm.channel_cfg=${CHANNEL_CFG_PATH} [optional arguments]

• CHANNEL_CFG_PATH: Path of channel_cfg. channel_cfg represents config for channel of the subnet searched out, used to specify different subnets for testing. An example for channel_cfg can be found here, and the usage can be found here.

Distillation

To test distillation method, you can use following command

python tools/${task}/test_${task}.py ${CONFIG_FILE} ${CHECKPOINT_PATH} [optional arguments]
