RuntimeError: Kaleido now requires that chrome/chromium is installed separately. Kaleido will try to detect it automatically, but the environmental error "BROWSER_PATH" can also be set
За последние годы я много раз использовал эту схему для рисования диаграмм, все было нормально. Согласно истории выпусков пакета Kaleido pypi.org, Kaleido был вчера обновлен до версии 0.4.2.
Что такое chrome/chromium? В PyPi такого пакета нет. Есть ли у кого-нибудь идеи, как исправить ошибку?
