In this example, we have two arrays,array1andarray2. We use thenumpy.concatenate()function to join these two arrays end-to-end, resulting in a new array that includes all elements from both input arrays in their original order. The resulting array,result, is then printed to the console. ...
错误提示 "need at least one array to concatenate" 表明在调用 concatenate 函数时,没有提供任何数组作为参数。这是因为在 concatenate 函数中,至少需要一个数组来进行拼接操作。 2. 检查代码调用 需要检查你的代码中调用 np.concatenate() 的部分,确认是否有数组作为参数传递给该函数。例如,正确的调用方式应该是这...
When one or more of the arrays to be concatenated is a MaskedArray, this function will return a MaskedArray object instead of an ndarray, but the input masks arenotpreserved. In cases where a MaskedArray is expected as input, use the ma.concatenate function from the masked array module ins...
>>> y = np.array([[7, 8]]) >>> np.concatenate((x,y), axis=0) array([[3, 4], [5, 6], [7, 8]]) In the above code, we first import the NumPy library as 'np'. We then create two arrays 'x' and 'y' using the 'np.array()' function. The array 'x' contains two...

When one or more of the arrays to be concatenated is a MaskedArray, this function will return a MaskedArray object instead of an ndarray, but the input masks arenotpreserved. In cases where a MaskedArray is expected as input, use the ma.concatenate function from the masked array module ins...
concatenate : Concatenate function that preserves input masks. array_split : Split an array into multiple sub-arrays of equal or near-equal size. split : Split array into a list of multiple sub-arrays of equal size. hsplit : Split array into multiple sub-arrays horizontally (column wise) ...
