成功解决raise ValueError("Unknown label type: %s" % repr(ys))ValueError: Unknown label type: (array([24 解决问题 raise ValueError("Unknown label type: %s" % repr(ys))ValueError: Unknown label type: (array([24 解决思路 错误:未知标签类型 解决方法 对当前特征变量进行声明或者定义数据类型即可,...
核查导致“unknown label type”错误的输入数据,特别是标签数据的格式和类型。 可以使用print(type(labels[0]))来检查标签列表中第一个元素的类型。 如果标签是浮点数、列表、字典或其他非预期的类型,就会引发此错误。 修改或转换标签: 根据库或工具的要求,修改或转换标签数据到正确的类型。 如果标签是浮点数,可...
如果sklearn 导入的分类算法,即逻辑回归是在连续目标变量上训练的,它会抛出ValueError: Unknown label type:'continuous'。 代码: importnumpyasnpfromsklearn.linear_modelimportLogisticRegression input_var=np.array([[1.1,1.2,1.5,1.6],[0.5,0.9,0.6,0.8]]) target_var=np.array([1.4,0.4]) classifier_logis...
The "Unknown label type: 'unknown'" error is typically encountered when working with the Y values in scikit-learn. The error arises due to a discrepancy between the expected input format and the actual data passed. This mismatch could be between Array and DataFrame or 1D list and 2D list,...
For example I can pass y=np.array([1., 1., 0., 1,0]) to fit and don't get an error. Even though there could be, based on the type alone, missing values (in the form of NaNs) in it. If passing floats as y fora classification problem is "legal", then I think passing Int...
