importerror: cannot import name 'display' from 'ipython.core.display'"

Not specified by the original author.

TL;DR

This is the same failure as the capitalized version: IPython 9 removed the ipython.core.display re-export, so display must come from IPython.display. Paste from IPython.display import display, HTML, Image at the top of the notebook. Then check the environment for a partially upgraded IPython, because half-upgraded installs produce the identical message for a different reason.

importerror: cannot import name 'display' from 'ipython.core.display'

Use this when

• Terminal or log output shows the lowercase importerror: phrasing for ipython.core.display.
• The failure appeared after pip install --upgrade ipython or a fresh environment build.
• A dependency log or CI log captured the lowercase traceback line.

Not for this skill when

• The message names ipykernel as missing. Install ipykernel instead.
• The import works in a terminal but fails inside the notebook. That is a kernel-vs-environment mismatch.

Steps

1. In the failing cell, replace the import with from IPython.display import display. Verify: the cell executes without error.
2. Check for a split-brain install: pip show ipython | grep Location and python -c "import IPython; print(IPython.__file__)". Verify: both point at the same site-packages.
3. If the paths disagree, uninstall twice and reinstall once: pip uninstall -y ipython, repeat, then pip install ipython. Verify: one location, one version.
4. Reinstall the kernel spec from the cleaned environment: python -m ipykernel install --user --name [env-name]. Verify: jupyter kernelspec list shows the new spec.
5. Re-run the notebook top to bottom in the re-registered kernel. Verify: no ImportError on any display import.

Variant phrasings

cannot import name display ipython

The short search form. Same removal, same fix.

display import error ipython 9

Version-tagged phrasing. Confirms the IPython 9 removal is the cause.

ipython display ImportError lowercase

Log-scraped phrasing. Fix path is unchanged.

Compatibility: IPython 8/9, pip and conda installs. The fix is version-agnostic once the import points at IPython.display.

Why it happens

Lowercase importerror: usually means the line was copied from a terminal traceback or a log aggregator rather than typed by a human. The underlying cause is the same IPython 9 removal, but log-sourced reports are also where half-upgraded environments show up, so this variant doubles as a prompt to check for two IPython copies fighting in one environment.

Edge cases / pitfalls

• Running pip install ipython while the notebook kernel runs from a different python does not fix the notebook. Fix the kernel's environment.
• Conda and pip mixing can leave IPython in one site-packages and ipython metadata in another. Check both.
