How to run the parse function with GPU in rst_parser package?

My code are as follows:
```
with pd.read_csv(path, chunksize=10) as reader:  # 每次读取1000行
    results = []
    for chunk in reader:
        data = chunk['Data'].tolist()
        tree_results, dis_results = rst_parser.parse(data)
        results.extend(dis_results)  # 收集结果
```
I need to parse thousands of sentences, however I cannot find where can I use GPU to process.
Thank you.
