Question

需要有关此代码段的帮助：我有一组pickle数据。文件名为EEG-ClenchingA.pickle，其中A是整数。此外，另一个代码通过串行端口连续读取数据，并且每次读取一组新数据时（一组我的意思是一分钟长数据=有15个通道和128 Hz采样率=> 128 * 60 = 7680即每分钟我得到一个7680 * 15的数组作为输入。），我在另一个index.pickle文件中递增计数器。让我们说index.pickle中的计数器值现在是X.然后下一个数据集为1 min read保存为EEG-ClenchingX.pickle。然后index.pickle中的计数器值更新为X + 1所以在这里，我写了一个代码，每分钟生成一次数据。可悲的是，我的动画只更新了一次，虽然数据文件存在，而index.pickle中的计数器每分钟更新一次（我可以看到它发生）。

请帮助！
