Integrate SwanLab for offline/online experiment tracking and local visualization

[ShaohonChen]

What does this PR do?

This PR introduces SwanLab, a lightweight open-source experiment tracking tool, as a new logging option for the training framework. The integration provides both online and offline tracking capabilities, along with a local dashboard for visualizing results.

SwanLab has previously supported tracking the Transformers training framework through external callbacks (find more information here), serving a wide range of users—especially those in regions with limited network connectivity, such as China. With this official integration, we aim to further enhance the developer experience by making tracking more seamless and user-friendly.

• Offline Mode: Use a local dashboard to visualize training logs without an internet connection.

2. Hardware Monitoring:

• Automatically tracks GPU usage, power consumption, temperature, and other hardware metrics.
• Supports NVIDIA GPUs and Huawei Ascend NPUs.

3. Remote Access:

• View training progress remotely via the SwanLab web interface or mobile app.

4. Local Dashboard:

Usage guidline

Step 0: Set Up code and environment

Following the transformers official text classification example:

# prepare code and environments
git clone https://github.com/huggingface/transformers
cd transformers
pip install -e .
cd examples/pytorch/text-classification
pip install -r requirements.txt
# 

Step 1: Set Up SwanLab Online Tracking

Install:

pip install swanlab

To use SwanLab's online tracking, log in to the SwanLab website and obtain your API key from the Settings page. Then, authenticate using the following command:

swanlab login

If you prefer offline mode, skip this step.

Step 2: Configure SwanLab as the Logger and run example

To enable SwanLab as the experiment tracker, add --use_swanlab to your training command. For example, using the workflow:

python run_glue.py \
  --model_name_or_path google-bert/bert-base-cased \
  --dataset_name imdb  \
  --do_train \
  --do_predict \
  --max_seq_length 128 \
  --per_device_train_batch_size 32 \
  --learning_rate 2e-5 \
  --num_train_epochs 3 \
  --output_dir /tmp/imdb/

visualization demo

If you want to use local tracking, you simply set environment variable following:

# Linux & Mac
export SWANLAB_MODE = "local"
# Win
$env:SWANLAB_MODE = "local"

Alternatively, you can configure SwanLab using environment variables:

export SWANLAB_API_KEY=<your_api_key>          # Set API key for online tracking
export SWANLAB_LOG_DIR=<local_log_path>        # Set local log directory
export SWANLAB_MODE=<mode>                    # Set tracking mode: cloud (default), cloud-only, local, or disabled

Step 3: View Training Logs

After logging in, you will see a confirmation message:

• Online Tracking: View logs on the SwanLab website.

For more details, refer to the SwanLab Cloud Documentation.

• Offline Tracking: Use the local dashboard to visualize logs:
