With the RAPIDS GPU DataFrame, data can be loaded onto GPUs using a Pandas-like interface, and then used for various connected machine learning and graph analytics algorithms without ever leaving the GPU. This level of interoperability is made possible through libraries like Apache Arrow and allows...
python中判断一个dataframe非空 DataFrame有一个属性为empty,直接用DataFrame.empty判断就行。 如果df为空,则 df.empty 返回 True,反之 返回False。 注意empty后面不要加()。 学习tips:查好你自己所用的Pandas对应的版本,在官网上下载Pandas 使用的pdf手册,直接搜索“empty”,就可找到有...数据...
