Dask DataFrame was originally designed to scale Pandas, orchestrating many Pandas DataFrames spread across many CPUs into a cohesive parallel DataFrame. Because cuDF currently implements only a subset of the Pandas API, not all Dask DataFrame operations work with cuDF. 3. 最装逼的办法就是只用pandas...

>>> temp_df = movies_df.append(movies_df) # make a new copy>>> temp_df.drop_duplicates(inplace=True, keep=False)>>> temp_df.shape(0, 11) 1. 由于所有行都是重复的,因此keep = False丢弃了所有行,导致剩下零行。如果您想知道为什么要这样做,原因之一是它允许您查找数据集中的所有重复项。...
