Question

我正在运行前馈神经网络，并希望获得一条线的混淆矩阵

sklearn.metrics.confusion_matrix(goldLabel_array, predictions, sample_weight=None, labels=None)

但是当我运行它时，它在标题中显示了错误消息。我安装了scikit-learn和sklearn。当我运行“点列表”时，将列出sklearn，但版本为0.0。当我运行conda install sklearn时，它会为我提供以下信息：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with current_repodata.json, will retry with next repodata source.

该错误与安装无关。它告诉您尚未将库导入到在代码中调用它的位置。

编辑是直接导入confusion_matrix，因此需要直接引用，而不是通过sklearn引用。

confusion_matrix(goldLabel_array, predictions, sample_weight=None, labels=None)

与您的其他通话相同。
