Błąd z jupyter notebook

Question

Witam mam taki problem, chcę odpalić jupyter notebook i wywala mi kernel error na samym końcu błędu jest że nie znaleziono pliku lub ścieżki do folderu którego już od dawna nie mam na komputerze. Ile nowych folderów i envów bym nie zrobił zawsze wywala ten sam błąd! próbowałem odinstalować jupyter notebook i co? wywala że nawet nie mam tego zainstalowanego XD o co chodzi z tym dziadostwem? bo to już zaczyna robić się śmieszne. Dodam że pracuję na macu.

A jakbyś spróbował odpalić jupyter notebook poza virtual env?

Answer 1

A spróbuj w ten sposób

python -m ipykernel install --user

Albo

python3 -m ipykernel install --user
