TypeError:分析器()缺少一个必需的位置参数：'self‘

Question

当试图从https://github.com/evidentlyai/evidently/blob/main/evidently/tutorials/historical_drift_visualization.ipynb执行公开可用的代码(第200-205行“特性漂移”部分)时，我会收到以下错误

TypeError                                 Traceback (most recent call last)

TypeError: analyzers() missing 1 required positional argument: 'self'

在尝试执行第195-196行(部分:数据漂移)之后，我获得了一个类似的错误。

我使用Python3.8.8。

我显然安装了一些问题。在成功安装(pip install --user Evidently)之后，我得到了以下错误：

mitosheet 0.1.361需要plotly==5.3.0，但您的策略是4.12.0，它不兼容

在(pip install plotly==5.3.0)皮普告诉我

0.1.34.dev0需要plotly~=4.12.0，但是您有一个不兼容的5.3.0。

Answer 1

只需在前面加上括号即可。

例如：

data_and_target_drift_report = Dashboard(tabs=[DataDriftTab(),CatTargetDriftTab()])
