UFuncTypeError: ufunc ‘add‘ did not contain a loop with signature matching types (dtype(‘<U14‘), dty

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)

----> 3 print("demo_data(原来):" + demo_data)
      4 print("demo_data_add(添加):" + demo_data_add)
