我正在处理重新采样数据帧，它可以在几小时、几天、几分钟内工作，但重新采样的时间不会少于秒。即使时间跨度很短，程序也会挂起。那么我错过了什么吗？
我尝试了 0.000001S、U 等...到目前为止没有任何效果。
我的时间格式：2015-08-29 19:30:47.015506
您可以看到变量 sf 代表重采样频率。
grph = df.set_index('Date and Time').resample(sf, len).astype(int)
如何以微秒粒度对数据帧重新采样？
sf = "1U" #for one microsecond
对于毫秒/微秒/秒，使用：
L milliseonds
U microseconds
S seconds
