如何为图像的每一帧将2D数组写入csv？

Question

我有一个getX()，它为图像的每一帧提供2D array(shape=(18,2))作为输出。我想将此不断更新的数组添加到CSV。

我使用了以下代码。但这只给我一行（可能只有一帧）。

with open("data.csv",mode ='w') as csvfile:
            wr = csv.writer(csvfile, quoting = csv.QUOTE_ALL,dialect="excel")
            get_val = oneObject.getX(currentFrameIndex)
            for  humanPos in get_val:
                wr.writerow(humanPos)

为什么不累积子数组，然后仅使用const compareBySliceA = (prevSate: RootState, newState: RootState) => { // This is just an example you can compare inner of Slice A if (newState.SliceA === prevState.SliceB) { return true } return false; }; const getDerivedSliceB (state: RootState): List<any> => state.SliceB.filter(ElementB => ElementB.visible) const createComparatorSelector = createSelectorCreator( defaultMemoize, compareBySliceA, ); export const myDeepSelector = createComparatorSelector( (state: RootState) => state, (state: RootState): List<any> => getDerivedSliceB(state), ); 一次写入CSV？
