ValueError：无法找到可以处理输入的数据适配器：<class 'numpy.ndarray'> ,<class 'pandas.core.frame.DataFrame'>
[英]ValueError: Failed to find data adapter that can handle input: <class 'numpy.ndarray'>, <class 'pandas.core.frame.DataFrame'>
问题描述
In my code, my model is compiling fine but when I am using pd.get_dummies(pd.Series(test_labels)) to get the labels for the validation images, it gives me the following error.
在我的代码中，我的模型编译得很好，但是当我使用pd.get_dummies(pd.Series(test_labels))获取验证图像的标签时，它给了我以下错误。
File "train_model.py", line 43, in <module>
pd.get_dummies(pd.Series(test_labels))])

_type_name(x), _type_name(y)))
ValueError: Failed to find data adapter that can handle input: <class 'numpy.ndarray'>, <class 'pandas.core.frame.DataFrame'>
What seems to be the issue?似乎是什么问题？ My model is a simple tensorflow sequential model.我的模型是一个简单的 tensorflow 序列模型。

That is because pd.get_dummies gives a pd.DataFrame .那是因为pd.get_dummies给出了pd.DataFrame 。 You need to convert that to numpy.ndarray type.您需要将其转换为numpy.ndarray类型。
Try尝试
pd.get_dummeis(pd.Series(test_labels)).to_numpy()
