|
|

|
## Training process
|
||||||
|
|
||||||
|
### Usage
|
||||||
|
|
||||||
|
- Ascend: sh run_train.sh Ascend [DEVICE_NUM] [SERVER_IP(x.x.x.x)] [VISIABLE_DEVICES(0,1,2,3,4,5,6,7)] [DATASET_PATH] [CKPT_PATH]
|
||||||
|
|
||||||
|
|
||||||
|
### Launch
|
||||||
|
|
||||||
|
```
|
||||||
|
# training example
|
||||||
|
Ascend: sh run_train.sh Ascend 8 192.168.0.1 0,1,2,3,4,5,6,7 ~/imagenet/train/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Result
|
||||||
|
|
||||||
|
Training result will be stored in the example path. Checkpoints will be stored at `. /checkpoint` by default, and training log will be redirected to `./train/train.log` like followings.
|
||||||
|
|
||||||
|
```
|
||||||
|
epoch: [ 0/200], step:[ 624/ 625], loss:[5.258/5.258], time:[140412.236], lr:[0.100]
|
||||||
|
epoch time: 140522.500, per step time: 224.836, avg loss: 5.258
|
||||||
|
epoch: [ 1/200], step:[ 624/ 625], loss:[3.917/3.917], time:[138221.250], lr:[0.200]
|
||||||
|
epoch time: 138331.250, per step time: 221.330, avg loss: 3.917
|
||||||
|
```
|
||||||
|
|
||||||
|
## Eval process
|
||||||
|
|
||||||
|
### Usage
|
||||||
|
|
||||||
|
- Ascend: sh run_infer.sh Ascend [DATASET_PATH] [CHECKPOINT_PATH]
|
||||||
|
|
||||||
|
### Launch
|
||||||
|
|
||||||
|
```
|
||||||
|
# infer example
|
||||||
|
Ascend: sh run_infer.sh Ascend ~/imagenet/val/ ~/train/mobilenet-200_625.ckpt
|
||||||
|
```
|
||||||
|
|
||||||
|
> checkpoint can be produced in training process.
|
||||||
|
|
||||||
|
### Result
|
||||||
|
|
||||||
|
Inference result will be stored in the example path, you can find result like the followings in `val.log`.
|
||||||
|
|
||||||
|
```
|
||||||
|
result: {'acc': 0.71976314102564111} ckpt=/path/to/checkpoint/mobilenet-200_625.ckpt
|
||||||
|
```
