h5py是一个用于在Python中读取和写入HDF5文件的库。HDF5(Hierarchical Data Format 5)是一种用于存储和组织大量数据的文件格式。在HDF5文件中,可以包含多个数据...
hdf5文件中的时间戳数据是纳秒整数,分布式表是datetime,写入前需要进行转换。 t1=select Aval0,Aval1,Aval2,Aval3,Aval4,datetime(nanotimestamp(index)) as times from hdf5::loadHDF5( dataFilePath,datasetName) dfsTable=loadTable(dfsPath,"kline_eth_usd_kline") dfsTable.append!(t1) 有用 回复 撰...
create database%注意,这是的/data与/label表示文件里的dataset.当我们定义.proto文件的网络时,一定要注意:top:分别也要为data和label.h5create('train.hdf5','/data',size(trainData),'Datatype','double'); h5create('train.hdf5','/label',size(trainLabels),'Datatype','double'); h5write('train.hd...
