|
## Count number of parameters
|
|
|
|
```shell
|
|
python tools/analysis_tools/count_parameters.py ${CONFIG_FILE}
|
|
```
|
|
|
|
An example:
|
|
|
|
```shell
|
|
python tools/analysis_tools/count_parameters.py configs/selfsup/mocov2/mocov2_resnet50_8xb32-coslr-200e_in1k.py
|
|
```
|
|
|
|
## Publish a model
|
|
|
|
Before you publish a model, you may want to
|
|
|
|
- Convert model weights to CPU tensors.
|
|
- Delete the optimizer states.
|
|
- Compute the hash of the checkpoint file and append the hash id to the filename.
|
|
|
|
```shell
|
|
python tools/model_converters/publish_model.py ${INPUT_FILENAME} ${OUTPUT_FILENAME}
|
|
```
|
|
|
|
An example:
|
|
|
|
```shell
|
|
python tools/model_converters/publish_model.py YOUR/PATH/epoch_100.pth YOUR/PATH/epoch_100_output.pth
|
|
```
|
|
|
|
## Reproducibility
|
|
|
|
If you want to make your performance exactly reproducible, please set `--cfg-options randomness.deterministic=True` to train the final model. Note that this will switch off `torch.backends.cudnn.benchmark` and slow down the training speed.
|
|
|
|
## Log Analysis
|
|
|
|
`tools/analysis_tools/analyze_logs.py` plots loss/lr curves given a training
|
|
log file. Run `pip install seaborn` first to install the dependency.
|
|
|
|
```shell
|
|
python tools/analysis_tools/analyze_logs.py plot_curve [--keys ${KEYS}] [--title ${TITLE}] [--legend ${LEGEND}] [--backend ${BACKEND}] [--style ${STYLE}] [--out ${OUT_FILE}]
|
|
```
|
|
|
|
<div align="center">

|
<img src="https://raw.githubusercontent.com/open-mmlab/mmdetection/master/resources/loss_curve.png" width="400" />
|
|
</div>
|
|
|
|
Examples:
|
|
|
|
- Plot the classification loss of some run.
|
|
|
|
```shell
|
|
python tools/analysis_tools/analyze_logs.py plot_curve log.json --keys loss_dense --legend loss_dense
|
|
```
|
|
|
|
- Plot the classification and regression loss of some run, and save the figure to a pdf.
|
|
|
|
```shell
|
|
python tools/analysis_tools/analyze_logs.py plot_curve log.json --keys loss_dense loss_single --out losses.pdf
|
|
```
|
|
|
|
- Compare the loss of two runs in the same figure.
|
|
|
|
```shell
|
|
python tools/analysis_tools/analyze_logs.py plot_curve log1.json log2.json --keys loss --legend run1 run2
|
|
```
|
|
|
|
- Compute the average training speed.
|
|
|
|
```shell
|
|
python tools/analysis_tools/analyze_logs.py cal_train_time log.json [--include-outliers]
|
|
```
|
|
|
|
The output is expected to be like the following.
|
|
|
|
```text
|
|
-----Analyze train time of work_dirs/some_exp/20190611_192040.log.json-----
|
|
slowest epoch 11, average time is 1.2024
|
|
fastest epoch 1, average time is 1.1909
|
|
time std over epochs is 0.0028
|
|
average iter time: 1.1959 s/iter
|
|
```
