import pyupbit market_price = pyupbit.get_ohlcv("KRW-ETH", interval="minute1") print(market_price.resample('2T')) ------------------------------------------------------------------------------------- DatetimeIndexResampler [freq=<2 * Minutes>, axis=0, closed=left, label=left, convention=start, origin=start_day] 에러가 나서, 찾아보니까 Starting from 0.18.0, resample itself is a deferred operation, meaning that you first have to call a method (in this case mean()) to perform the actual resampling: 판다스 버전이 높아서 난 에러인것 같습니다. import pandas as pd print( pd. __version__ ) ------------------------------------ 1.1.3 market_price.resample('2T').mean() 로 수정하니까 정상 출력이 됩니다. 참고하세요~ https://stackoverflow.com/questions/37723906/pandas-resample-does-not-work-properly
