I/O packege for Julia
HDF5
Description
HDF5 is a data model, library, and file format for storing and managing data. It supports an unlimited variety of datatypes, and is designed for flexible and efficient I/O and for high volume and complex data.
Installation
julia>]
pkg> add HDF5Usage
Save data to a file
using HDF5, Date
Today = Dates.today()
output = Dict{String, Any}()
output["Para/Ma"] = Ma
output["Grid"] = grids
output["Flow"] = flow
h5file = h5open("$Path/$Today-example-Ma$(Ma).h5", "w")
for (key, value) in output
write(h5file, key, value)
end
close(h5file)Load data from a file
using HDF5
filename = "$Path/example.h5"
h5file = h5open(filename, "r")
input = read(h5file)
close(h5file)JLD2
JLD2 saves and loads Julia data structures in a format comprising a subset of HDF5, without any dependency on the HDF5 C library. JLD2 is able to read most HDF5 files created by other HDF5 implementations supporting HDF5 File Format Specification Version 3.0 (i.e. libhdf5 1.10 or later) and similarly those should be able to read the files that JLD2 produces. JLD2 provides read-only support for files created with the JLD package. — the author of pakege
My opinion: This is a I/O lib based on HDF5 but much more conviniant than HDF5 itself for Julia user.
Usage
@save "filename.h5" data
@load "filename.h5"
