Я использовал пример загрузки файла на этом веб-сайте в моем Jupyter notebook на моем компьютере с Windows 10 с Visual Studio Code. Пример выглядит так:

     import ipywidgets as widgets
widgets.FileUpload(
    accept='',  # Accepted file extension e.g. '.txt', '.pdf', 'image/*', 'image/*,.pdf'
    multiple=False  # True to accept multiple files upload else False
)
 

и это выглядит так на моем компьютере:

Однако, когда я выбираю любое изображение (* .jpg или * .png) или любой файл, я получаю следующее сообщение об ошибке в консоли инструментов разработчика:

 FATAL ERROR: Error::New napi_get_last_error_info

Кто-нибудь знает, почему это происходит?

Прежде чем я запустил приведенный выше код загрузки файлов, я установил в свой PowerShell следующее:

 pip install Pillow 
pip install scikit-image
 

и похоже, что оба пакета успешно установлены без сообщений об ошибках.

Я использую следующую версию python:

 Python 3.7.8 (tags/v3.7.8:4b47a5b6ba, Jun 28 2020, 08:53:46) [MSC v.1916 64 bit (AMD64)] on win32
