ImportError:无法导入名称“签名”

Question

我正在尝试导入recmetrics包，我已经完成了其他帖子中提到的所有操作，但它不起作用。 代码如下

import recmetrics

错误是

ImportErrorTraceback (most recent call last)
<ipython-input-> in <module>
      5 import numpy as np
      6 from funcsigs import signature
----> 7 import recmetrics

      6 from sklearn.metrics import roc_curve, auc, precision_recall_curve, average_precision_score
----> 7 from sklearn.utils.fixes import signature
  
ImportError: cannot import name 'signature'

我尝试了以下步骤：

!pip freeze | grep recmetrics
recmetrics==0.0.12

首先，我尝试：

from sklearn.utils.fixes import signature

然后我试了一下：

from funcsigs import signature

它们中没有一个能工作，你能告诉我为什么不能工作吗。我使用的python版本是3.6.10 | Anaconda

我正在使用Amazonsage maker，我想知道如何在~/anaconda3/envs/python3/lib/python3.6/sitepackages/recmetrics/__init__.py中进行搜索 将from sklearn.utils.fixes import signature更改为from funcsigs import signature

I had to manually change in the plots.py Instead of from sklearn.utils.fixes import signature use from funcsigs import signature
