Usage
This extension enables opening HDF5 files in a JupyterLab tab and exploring HDF5 files in Jupyter notebooks.
In JupyterLab
You can double-click on an HDF5 file or right-click Open with -> h5web to launch a tab.
This tab is composed of a sidebar, where you can explore the structure of the HDF5 file, and of a main area where the visualization of the selected entity takes place. This visualization is controlled by the upper-right button that can toggle between:
-
Display: visualize datasets using
Line
,Heatmap
orMatrix
visualizations. - Inspect: show the metadata and attributes of any entity
In Jupyter notebooks
To open a HDF5 file with H5Web, use the H5Web
widget in a notebook cell:
from jupyterlab_h5web import H5Web
H5Web('<path to the HDF5 file>')
The cell height can be resized with the handle at the bottom-right.
An example is provided in example.ipynb.
Supported file formats
jupyter-h5web detects HDF5 files based on their file extensions. The viewer works for the following extensions:
For other types of files, you can change the extension to one of the supported extensions or, if it is widespread, open an issue to discuss its support.
