这些输出是来自LightGBM库的警告信息,用于指示模型训练过程中出现了一些问题。如果您不想看到这些输出,可以在训练模型时设置verbosity参数。将verbosity设置为0可以禁止输出任何信息,将其设置为1可以输出进度条,将其设置为2可以输出进度和警告信息,将其设置为3可以输出调试信息。例如,以下代码将verbosity设置为0,禁止输出任何信息:
```python
import lightgbm as lgb
params = {
'boosting_type': 'gbdt',
'objective': 'binary',
'metric': 'auc',
'verbose': -1 # 设置verbosity为-1
}
train_data = lgb.Dataset(X_train, label=y_train)
model = lgb.train(params, train_data, num_boost_round=100)
```
这样,就不会再输出任何警告信息了。当然,这些警告信息有可能是有用的,可以帮助您发现模型训练过程中出现的问题,因此建议在调试模型时保留这些信息。

git binary diffs are not supported.
This error message usually indicates that you are trying to view a binary file in Git using the "git diff" command. Git is designed to handle text files, and it cannot display differences between binary files in a meaningful way.
To resolve this issue, you can try using a different tool to view the binary file, such as a hex editor or a dedicated diff tool for binary files. Alternatively, you can tell Git to treat the file as a binary file by adding a "binary" attribute to the file's Git attributes file. This will prevent Git from attempting to display diffs for the file.
To add the "binary" attribute to a file, create or edit the .gitattributes file in the root of your repository and add the following line:
```
path/to/binary/file binary
```
Replace "path/to/binary/file" with the path to your binary file. After adding this attribute, Git will treat the file as a binary file and will not attempt to show diffs for it.

I'm sorry, but without any context or information about what you are referring to, I cannot provide a meaningful response. Could you please provide more details or clarify your question?
