与SQL Server连接的Python（HY105错误）参数类型HY105无效

我试图将CSV添加到python代码中，并使用LR、LDA和各种其他算法来测试它们的评分结果。 然后我想在SQLServer中以表的形式显示结果。 我得到错误“无效的参数类型。参数索引=0，参数类型=numpy.ndarray HY105” 如有补充，将不胜感激。 代码如下：

你能展示一下pythonTest表的格式吗？我假设

cv_results

不是本机数据类型pythontest表有6列，数据类型为nvarchar（100）。cv_results的类型为numpy.ndarray。我认为这是造成问题的原因之一。对此有何建议？您需要将其转换为元组或列表，以便show驱动程序能够理解它。您能显示pythonTest表的格式吗？我假设
