  1. Mac platforms now builds library with '-O3' optimization when the default clang compiler is used. Compatibility report for the hdf5 library between 1.8.13 and 1.8.
  2. HDF5 version 1.8.10 released on 2012-10-26 INTRODUCTION This document describes the differences between HDF5-1.8.9 and HDF5 1.8.10, and contains information on the platforms tested and known problems in HDF5-1.8.10.

HDF5PKGCONFIGNAME: A name to query pkg-config for. If none of these options are specified, h5py will query pkg-config by default for hdf5, or hdf5-openmpi if building with MPI support. HDF5MPI=ON to build with MPI integration - see Building against Parallel HDF5. HDF5VERSION to force a specified HDF5 version. In most cases, you don’t need. Oct 22, 2018 If you cannot access HDF5 files then you do not have these packages. You can obtain them from HERE. On Mac OS X, clicking on an HDF5 file brings up an empty HDFView. If you click on an HDF5 file on the Mac, it will bring up HDFView. However, the HDF5 file that you clicked on will not be opened in HDFView.

HDF5 is a node module for reading and writing the HDF5 file format.

Documentation

API documentation is available at http://hdf-ni.github.io/hdf5.node

See http://hdf-ni.github.io/hdf5.node/doc/install-setup.html for the native requirements and details. If your native hdf5 libraries aren't at the default you can set the path with --hdf5_home_linux switch on this project as well as dependent projects.

For mac and windows the switches are --hdf5_home_mac & --hdf5_home_win

To install with yarn first need to configure so it knows where the libraries are:

Note: If node-gyp isn't installed

Notes on Recent Releases

  • Note: Release v0.3.5

    • Strictly for building on Windows. Tested with VS 2017
  • Note: Release v0.3.4

    • Reference attributes on datasets and groups are now available properties.
    • Reserved propeties such as type, rank, rows etc. are now settable in options for dataset functions.
    • Typescript definition files now available.
    • For static native linkng, link_type command line switch is provided in binding.gyp(darwin,win untested).
    • Added custom 64 bit signed (Int64) and unsigned (Uint64) integer attributes read/write since they aren't yet supported by javascript.
    • Added a file method enableSingleWriteMultiRead (if native version older than 1.10.x it is a noop).
    • Synchronous iterate and visit is now available on file and group children.
    • Bug fixes on dimensioning have been made
  • Note: asynchronous i/o is coming but not in this release

  • Note: Release v0.3.3 Minor fix on fixed length of strings in array. Handles the situation where the strings are contiguous without all having null bytes.

  • Note: Release v0.3.2 tested with nodejs v6.11.2, v7.5.0 and v8.4.0. Code was changed to allow v8.4.0 to work while still working with the earlier versions. It may work back as far as v4.2.1 let me know if you have a version in between that needs testing. Variable length array of strings can be be read as regions.

  • Note: Release v0.3.1 is based on new V8 API changes coming with nodejs v7.

  • Note: Release v0.1.0 was built with nodejs v4.2.1. If you want nodejs v0.12.x then stay with release v0.0.20. npm will continue with nodejs v4.x.x line and any fixes or features needed by prior versions will be from github branches.

  • Note: Release v0.0.20 is for prebuilts with hdf5-1.8.15-patch1. If you want hdf5-1.8.14 stay with v0.0.19.

Philosophy

This module, hdf5.node, is intended to be a pure API for reading and writing HDF5 files. Graphical user interfaces or other layers should be implemented in separate modules.

Unlike other languages that wrap hdf5 API's this interface takes advantage of the compatibility of V8 and HDF5. The result is a direct map to javascript behavior with the least amount of data copying and coding tasks for the user. Hopefully you won't need to write yet another layer in your code to accomplish your goals.

Other Feature Notes

The node::Buffer and streams are being investigated so native hdf5 data's only destination is client browser window or client in general.

Dimension Scales

Mostly implemented (missing H5DSiterate_scales[ found a way to make callback functions from te native side and looking to finish this and use the technique for other h5 iterators])

High-level Functions for Region References, Hyperslabs, and Bit-fields

Writing an interface based on the standard hdf5 library. Currently you can write and read a subset from a two rank dataset. Other ranks may work yet are untested. See tutorial http://hdf-ni.github.io/hdf5.node/tut/subset_tutorial.html for example applied to node Buffers.

Filters and Compression

Hdf5 For Mac Software

Testing filters and compression. Have the gzip filter working. For some applications getting the uncompressed data from the h5 would reduce the number of compressions and decompressions. For example an image could be sent to client before unzipping and rezipping on the server side.

Third party filters can be used. Those do take separate compiled libraries yet are independent. They get picked up by native hdf5 from the HDF5_PLUGIN_PATH.

While there are many sprawling departments and executives within the Church of the Virtual Saints to handle the functions of running a starfaring civilization, there is only one ultimate authority - the Hierarch. This person, drawn from one of the powerful o. The Vodyani worship the Virtual Endless, and scour the galaxy seeking ancient temples while devouring lesser beings.

Image

The h5im namespace is being designed to meet the Image Spec 1.2 http://www.hdfgroup.org/HDF5/doc/ADGuide/ImageSpec.html. Hyperslabs/regions of images can now be read.

Contributors

  • Christian Nienhaus (@NINI1988) added typescript definitions and many pull requests and bug fixes for hdf5 native calls.
  • John Shumway (@shumway) refurbished the documentation when the project was split into an organization.

Mac OS X Lion: Use Brew

If you're on Mac OS X Lion (10.7), you may run into issues. If you're less inclined to get elbow-deep in computer problems, you can just use Homebrew (http://mxcl.github.io/homebrew/), a really nice package manager for Mac OS X. MacPorts and Fink can both be nightmares, but Homebrew manages to do everything hassle-free.

You can install HDF5 using Homebrew by running:

UPDATE: HDF5 has since moved to Homebrew-Science (https://github.com/Homebrew/homebrew-science). You can 'tap' into Homebrew Science to get to the HDF5 recipe.

Configuring

I am using the HDF5 libraries for various software tools available through the CRSim Software repository http://software.crsim.utah.edu/ - specifically, C++ programs using the C++ interface to HDF5 - necessitating the --enable-cxx configure argument:

You can optionally use the configure arguments --enable-static-exe --enable-static, though in my experience these aren't necessary to build (and link to) HDF5.

Errors

You may run into problems during make check, something looking like this:

The solution, as mentioned here http://kartadikaria.wordpress.com/2011/10/06/how-to-install-hdf5-macintosh-lion/, is to modify the configure flags for GNU compilers (the one used on Mac, if you're using gcc). Change the PROD_CFLAG for gcc compilers version 4 and up to use -O0 instead of the default -O3.


Python and HDF5

Hdf5 for mac versions

Link to quickstart: http://docs.h5py.org/en/latest/quick.html

Start by creating an HDF5 file object:

Now that you have a file object, create data sets:

(This is not a file, but a dataset object - this is similar to a Numpy array.)

Nvidia geforce gt 540m driver for windows 10. GeForce GTX 580M, GeForce GTX 570M, GeForce GTX 560M, GeForce GT 555M, GeForce GT 550M, GeForce GT 540M, GeForce GT 525M, GeForce GT 520M, GeForce GT 520MX GeForce 400M Series (Notebooks): GeForce GTX 485M, GeForce GTX 480M, GeForce GTX 470M, GeForce GTX 460M, GeForce GT 445M, GeForce GT 435M, GeForce GT 425M, GeForce GT 420M, GeForce GT 415M. This driver, version 352.84, is the first WHQL-certified and latest recommended driver for all pre-release Windows 10 testing. Exceptions: Notebooks supporting Hybrid Power technology are not supported (NVIDIA Optimus technology is supported).

Hdf5 Mac Os Install

HDF5 files are stored in a hierarchical way, with a 'directory'-like structure.

The file object is the root group, equivalent to / on a Unix system:
