H20 Driverless AI，无法加载自定义配方
H20 Driverless AI, Not able to load custom recipe
我正在使用 H2O DAI 1.9.0.6。我正在尝试在专家设置上加载自定义配方（使用自定义配方的 BERT 预保留模型）。我正在使用本地文件上传。但是上传没有发生。没有错误，没有进步。在那之后 activity 我无法在 RECIPE 选项卡下看到这个模型。
从下面 URL 中获取示例食谱并根据我的需要进行修改。感谢创建此食谱的人。

"""
Custom model class for using pretrained transformer models.
The class inherits :
- CustomModel that really is just a tag. It's there to make sure DAI knows it's a custom model.

Supported model architecture:
'bert', 'openai-gpt', 'gpt2', 'transfo-xl', 'xlnet', 'xlm-roberta',

How to use:
- You have already downloaded the weights, the vocab and the config file:
- Set _model_path as the folder where the weights, the vocab and the config file are stored.
- Set _model_name according to the pretrained architecture (e.g. bert-base-uncased).
- You want to to download the weights, the vocab and the config file:
- Set _model_link, _config_link and _vocab_link accordingly.
- _model_path is the folder where the weights, the vocab and the config file will be saved.
- Set _model_name according to the pretrained architecture (e.g. bert-base-uncased).
- Important:
_model_path needs to contain the name of the pretrained model architecture (e.g. bert or xlnet)
to be able to load the model correctly.
- Disable genetic algorithm in the expert setting.
