After the update to dev-python/mistune-3.0.1 jupyter-notebook no longer functions. Trying to run a notebook in a chrome causes an "INTERNAL ERR OR" message in the browser. Downgrading to 2.0.5 fixes it. The new mistune doesn't break jupyter-lab. Only jupyter-notebook. This is the trace in the console: Uncaught exception GET /notebooks/accuracy.ipynb (::1) HTTPServerRequest(protocol='http', host='localhost:8888', method='GET', uri='/notebooks/accuracy.ipynb', version='HTTP/1.1', remote_ip='::1') Traceback (most recent call last): File "/usr/lib/python3.11/site-packages/tornado/web.py", line 1786, in _execute result = await result ^^^^^^^^^^^^ File "/usr/lib/python3.11/site-packages/tornado/gen.py", line 786, in run yielded = self.gen.send(value) ^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/site-packages/notebook/notebook/handlers.py", line 94, in get self.write(self.render_template('notebook.html', ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/site-packages/notebook/base/handlers.py", line 515, in render_template return template.render(**ns) ^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/site-packages/jinja2/environment.py", line 1301, in render self.environment.handle_exception() File "/usr/lib/python3.11/site-packages/jinja2/environment.py", line 936, in handle_exception raise rewrite_traceback_stack(source=source) File "/usr/lib/python3.11/site-packages/notebook/templates/notebook.html", line 1, in top-level template code {% extends "page.html" %} File "/usr/lib/python3.11/site-packages/notebook/templates/page.html", line 187, in top-level template code {% block header %} File "/usr/lib/python3.11/site-packages/notebook/templates/notebook.html", line 115, in block 'header' {% for exporter in get_frontend_exporters() %} ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/site-packages/notebook/notebook/handlers.py", line 40, in get_frontend_exporters for name in get_export_names(): ^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/site-packages/nbconvert/exporters/base.py", line 150, in get_export_names e = get_exporter(exporter_name)(config=config) ^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/site-packages/nbconvert/exporters/base.py", line 109, in get_exporter exporter = [e for e in exporters if e.name == name or e.name == name.lower()][0].load() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/importlib/metadata/__init__.py", line 202, in load module = import_module(match.group('module')) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "<frozen importlib._bootstrap>", line 1204, in _gcd_import File "<frozen importlib._bootstrap>", line 1176, in _find_and_load File "<frozen importlib._bootstrap>", line 1126, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 1204, in _gcd_import File "<frozen importlib._bootstrap>", line 1176, in _find_and_load File "<frozen importlib._bootstrap>", line 1147, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 690, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 940, in exec_module File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed File "/usr/lib/python3.11/site-packages/nbconvert/__init__.py", line 7, in <module> from .exporters import * File "/usr/lib/python3.11/site-packages/nbconvert/exporters/__init__.py", line 4, in <module> from .html import HTMLExporter File "/usr/lib/python3.11/site-packages/nbconvert/exporters/html.py", line 28, in <module> from nbconvert.filters.markdown_mistune import IPythonRenderer, MarkdownWithMath File "/usr/lib/python3.11/site-packages/nbconvert/filters/markdown_mistune.py", line 17, in <module> from mistune import PLUGINS, BlockParser, HTMLRenderer, InlineParser, Markdown # type:ignore ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ImportError: cannot import name 'PLUGINS' from 'mistune' (/usr/lib/python3.11/site-packages/mistune/__init__.py) [E 16:26:12.406 NotebookApp] { "Host": "localhost:8888", "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7", "User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36" } [E 16:26:12.406 NotebookApp] 500 GET /notebooks/accuracy.ipynb (::1) 67.080000ms referer=None
