ufunc 'add' did not contain a loop with signature matching types (dtype('int

报错信息：

UFuncTypeError: ufunc 'add' did not contain a loop with signature matching types (dtype('<U14'), dtype('int64')) -> None

今天写了一小段关于“numpy.newaxis”的测试代码，在打印输出的时候。

原代码：


demo_data = np.arange(4)
demo_data_add = demo_data[:,np.newaxis]
print("demo_data(原来):" + demo_data)
print("demo_data_add(添加):" + demo_data_add)

执行后，报以下错误信息：


UFuncTypeError                            Traceback (most recent call last)

      2 demo_data_add = demo_data[:,np.newaxis]
----> 3 print("demo_data(原来):" + demo_data)
      4 print("demo_data_add(添加):" + demo_data_add)
