I am trying to create a 2 * 3 numpy array as below:
我正在尝试创建一个2 * 3 numpy数组,如下所示:
x_sample= np.array([31000,28.69,7055.47],[79000,3.9,16933.26]);
But I get:

You are missing brackets around the two lists.
您缺少两个列表的括号。
x_sample= np.array([[31000,28.69,7055.47],[79000,3.9,16933.26]])
The way it was written the dtype argument was receiving the value [79000,3.9,16933.26], which obviously cannot be interpreted as a valid NumPy data type and caused the error.
写入dtype参数的方式是接收值[79000,3.9,16933.26],这显然不能被解释为有效的NumPy数据类型并导致错误。

You can try
你可以试试
np.vstack(([31000,28.69,7055.47],[79000,3.9,16933.26]))
