Penzai 0.1.2
New features:
- Penzai's pretty printer Treescope can now be more easily extended to work with custom types, by defining the special method
__penzai_repr__
, which will be detected during pretty-printing. Renderings of these custom types can be built usingpenzai.treescope.repr_lib
, a stable extension API that can be used to implement__penzai_repr__
in a forwards-compatible way. (Note that the exact internal representation of Treescope renderings is still unstable and may change in the future; see the documentation forpenzai.treescope
for details.) - Added
pz.ts.basic_interactive_setup()
, which simplifies setting up the pretty-printer in an IPython notebook.
Bug fixes and improvements:
- Improved detection of mutable vs immutable objects during pretty-printing.
- Fixed detection of special methods
_repr_html_
and__penzai_repr__
to avoid objects that generate arbitrary attributes dynamically. - Copy-path buttons are no longer shown for the root node.
Documentation changes:
- Documentation has been added for how to extend
penzai.treescope
to render custom types in a stable way. - The right-hand sidebar now shows more detail in tutorial notebooks.
Penzai 0.1.1
Penzai 0.1.1 fixes a number of bugs and adds a few convenience features.
New features:
NamedArray
can now be converted automatically to a JAX array without unwrapping it if it has no more named axes (e.g. after callinguntag
).- Lifting JAX functions to operate over
NamedArray
s can be accomplished with less boilerplate usingpenzai.toolshed.auto_nmap
: if you setnjnp = auto_nmap.wrap_module(jnp)
, you can usenjnp.{method}
instead ofpz.nx.nmap(jnp.{method})
.
Bug fixes and improvements:
- Bugfix: Array data in array visualization tooltips now correctly accounts for slider offsets.
- Improvements to compatibility of
penzai.treescope
renderings:- Copy-path buttons no longer require internet access.
- Pretty-printed outputs should now appear in the correct location in JupyterLab.
- Perfomance improvements for non-Chrome browsers.
Documentation changes:
- Fixed typos and formatting issues.
- Fixed notebook output display bug in Firefox.
- Source links in ReadTheDocs now link to a specific commit.
- Cross-page links in ReadTheDocs now support hover tooltip previews.
