ImportError: cannot import name 'display' from 'IPython.core.display'

Not specified by the original author.

TL;DR

IPython 9 removed the old ipython.core.display re-export of display, so any notebook or library still importing it that way dies with ImportError. Change the import line to from IPython.display import display (same for HTML, Image, Markdown). Then grep the repo for other ipython.core.display imports so the next cell does not hit the same wall.

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

Use this when

• A notebook cell fails with ImportError naming ipython.core.display right after an IPython upgrade.
• The traceback points at a library file that does from ipython.core.display import display or HTML.
• You recently upgraded IPython past 8.x and old notebooks broke.

Not for this skill when

• The error is ModuleNotFoundError for ipykernel. That is a missing kernel package, a different fix.
• The kernel itself dies or segfaults. That is a binary/ABI problem, not an import path.

Steps

1. Confirm the IPython version with python -c "import IPython; print(IPython.__version__)". Verify: you see 9.x, where the old path is gone.
2. Find every old-style import: grep -rn "ipython.core.display" --include=*.py --include=*.ipynb .. Verify: you have the full list of files to change.
3. Replace from ipython.core.display import display with from IPython.display import display in each file. Verify: a fresh python -c "from IPython.display import display" imports cleanly.
4. Restart the kernel and re-run the failing cell top to bottom. Verify: no ImportError and outputs render.
5. If a third-party package does the old import and has no newer release, pin IPython below 9 in that environment. Verify: the package imports again in a fresh kernel.

Variant phrasings

importerror cannot import name display from ipython core display

The same failure with the ImportError prefix. Identical fix.

cannot import display from IPython after upgrade

The post-upgrade search phrasing. Same root cause, same one-line import change.

ipython.core.display deprecated

The historical framing. In current IPython the path is removed, not just deprecated.

Compatibility: IPython 8.x and 9.x. The from IPython.display import ... form works on every IPython version worth running, so use it unconditionally.

Why it happens

IPython moved its display helpers to the top-level IPython.display package years ago and kept ipython.core.display as a compatibility re-export. IPython 9 dropped that shim.

Edge cases / pitfalls

• Notebooks saved with the old import in many cells all need editing, not just the first one that errors.
• Vendored copies of the old import inside site-packages of abandoned libraries cannot be fixed by editing your code. Pin IPython or patch the library.

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.

TL;DR: IPython moved display from IPython.core.display to IPython.display. Change the import, or upgrade spacy to a release that did.

The error

ImportError: cannot import name 'display' from 'IPython.core.display'

Fix it

1. Replace the import:

   from IPython.display import display

   Expected: no import error.

2. If the bad import is inside spacy's displacy, upgrade spacy instead:

   pip install -U spacy

   Expected: new release uses the new path.

3. Verify:

   python -c "from IPython.display import display; print('ok')"

   Expected: prints ok.

When this applies

Use this when code does from IPython.core.display import display on modern IPython.

When it does not apply

If the error names a different IPython.core member, look up its new location. If IPython itself will not import, reinstall it.

Compatibility

Modern IPython (7+). IPython.display has re-exported display for years, so the new import works broadly.

Root cause

IPython reorganized its display machinery and made IPython.display the public namespace; the old IPython.core.display path stopped exporting every name. Code importing from the old path breaks.

Edge cases

HTML, Markdown, and SVG moved the same way; update all IPython.core.display imports in one pass. Libraries should import from IPython.display unconditionally now.

GitHub issue explosion/spacy#13871 reports ImportError: cannot import name 'display' from 'IPython.core.display' with a modern IPython installed, breaking spacy's displacy rendering. The verified answer: IPython moved display to the top-level IPython.display namespace, so the import becomes from IPython.display import display (spacy fixed it in a later release, so upgrading spacy also works).
