# Task Execution and Monitoring

## Launching an Evaluation Task

The program entry for the evaluation task is `run.py`. The usage is as follows:

```shell
python run.py $EXP {--slurm | --dlc | None} [-p PARTITION] [-q QUOTATYPE] [--debug] [-m MODE] [-r [REUSE]] [-w WORKDIR] [-l] [--dry-run] [--dump-eval-details]
```

Task Configuration (`$EXP`):

- `run.py` accepts a .py configuration file as task-related parameters, which must include the `datasets` and `models` fields.

  ```bash
  python run.py configs/eval_demo.py
  ```

- If no configuration file is provided, users can also specify models and datasets using `--models MODEL1 MODEL2 ...` and `--datasets DATASET1 DATASET2 ...`:

  ```bash
  python run.py --models hf_opt_350m hf_opt_125m --datasets siqa_gen winograd_ppl
  ```

- For HuggingFace related models, users can also define a model quickly in the command line through HuggingFace parameters and then specify datasets using `--datasets DATASET1 DATASET2 ...`.

  ```bash
  python run.py --datasets siqa_gen winograd_ppl --hf-type base --hf-path huggyllama/llama-7b
  ```

  Complete HuggingFace parameter descriptions:

  - `--hf-path`: HuggingFace model path
  - `--peft-path`: PEFT model path
  - `--tokenizer-path`: HuggingFace tokenizer path (if it's the same as the model path, it can be omitted)
  - `--model-kwargs`: Parameters for constructing the model
  - `--tokenizer-kwargs`: Parameters for constructing the tokenizer
  - `--max-out-len`: Maximum generated token count
  - `--max-seq-len`: Maximum sequence length the model can accept
  - `--batch-size`: Batch size
  - `--hf-num-gpus`: Number of GPUs required to run the model. Please note that this parameter is only used to determine the number of GPUs required to run the model, and does not affect the actual number of GPUs used for the task. Refer to [Efficient Evaluation](./evaluation.md) for more details.

Starting Methods:

- Running on local machine: `run.py $EXP`.
- Running with slurm: `run.py $EXP --slurm -p $PARTITION_name`.
- Running with dlc: `run.py $EXP --dlc --aliyun-cfg $AliYun_Cfg`
- Customized starting: `run.py $EXP`. Here, $EXP is the configuration file which includes the `eval` and `infer` fields. For detailed configurations, please refer to [Efficient Evaluation](./evaluation.md).

The parameter explanation is as follows:

- `-p`: Specify the slurm partition;
- `-q`: Specify the slurm quotatype (default is None), with optional values being reserved, auto, spot. This parameter may only be used in some slurm variants;
- `--debug`: When enabled, inference and evaluation tasks will run in single-process mode, and output will be echoed in real-time for debugging;
- `-m`: Running mode, default is `all`. It can be specified as `infer` to only run inference and obtain output results; if there are already model outputs in `{WORKDIR}`, it can be specified as `eval` to only run evaluation and obtain evaluation results; if the evaluation results are ready, it can be specified as `viz` to only run visualization, which summarizes the results in tables; if specified as `all`, a full run will be performed, which includes inference, evaluation, and visualization.
- `-r`: Reuse existing inference results, and skip the finished tasks. If followed by a timestamp, the result under that timestamp in the workspace path will be reused; otherwise, the latest result in the specified workspace path will be reused.
- `-w`: Specify the working path, default is `./outputs/default`.
- `-l`: Enable status reporting via Lark bot.
- `--dry-run`: When enabled, inference and evaluation tasks will be dispatched but won't actually run for debugging.
- `--dump-eval-details`: Default enabled，evaluation under the `results` folder will include more details, such as the correctness of each sample. Set `--dump-eval-details False` to disable it。

Using run mode `-m all` as an example, the overall execution flow is as follows:

1. Read the configuration file, parse out the model, dataset, evaluator, and other configuration information
2. The evaluation task mainly includes three stages: inference `infer`, evaluation `eval`, and visualization `viz`. After task division by Partitioner, they are handed over to Runner for parallel execution. Individual inference and evaluation tasks are abstracted into `OpenICLInferTask` and `OpenICLEvalTask` respectively.
3. After each stage ends, the visualization stage will read the evaluation results in `results/` to generate a table.

## Task Monitoring: Lark Bot

Users can enable real-time monitoring of task status by setting up a Lark bot. Please refer to [this document](https://open.feishu.cn/document/ukTMukTMukTM/ucTM5YjL3ETO24yNxkjN?lang=zh-CN#7a28964d) for setting up the Lark bot.

Configuration method:

1. Open the `configs/lark.py` file, and add the following line:

   ```python
   lark_bot_url = 'YOUR_WEBHOOK_URL'
   ```

   Typically, the Webhook URL is formatted like this: https://open.feishu.cn/open-apis/bot/v2/hook/xxxxxxxxxxxxxxxxx .

2. Inherit this file in the complete evaluation configuration:

   ```python
     from mmengine.config import read_base

     with read_base():
         from .lark import lark_bot_url

   ```

3. To avoid frequent messages from the bot becoming a nuisance, status updates are not automatically reported by default. You can start status reporting using `-l` or `--lark` when needed:

   ```bash
   python run.py configs/eval_demo.py -p {PARTITION} -l
   ```

## Run Results

All run results will be placed in `outputs/default/` directory by default, the directory structure is shown below:

```
outputs/default/
├── 20200220_120000
├── ...
├── 20230220_183030
│   ├── configs
│   ├── logs
│   │   ├── eval
│   │   └── infer
│   ├── predictions
│   │   └── MODEL1
│   └── results
│       └── MODEL1
```

Each timestamp contains the following content:

- configs folder, which stores the configuration files corresponding to each run with this timestamp as the output directory;
- logs folder, which stores the output log files of the inference and evaluation phases, each folder will store logs in subfolders by model;
- predictions folder, which stores the inferred json results, with a model subfolder;
- results folder, which stores the evaluated json results, with a model subfolder.

Also, all `-r` without specifying a corresponding timestamp will select the newest folder by sorting as the output directory.
