Версия nvcc остается прежней после обновления версии CUDA Toolkit. ⇐ Linux

[Anonymous]

Я установил CUDA Toolkit 12.6 Update 1 в Ubuntu 22.04 с помощью команды ниже (инструкции можно найти здесь):
wget https://developer.download.nvidia.com/c ... tu2204.pin
sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/c ... _amd64.deb
sudo dpkg -i cuda-repo-ubuntu2204-12-6-local_12.6.1-560.35.03-1_amd64.deb
sudo cp /var/cuda-repo-ubuntu2204-12-6-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get update
sudo apt-get -y install cuda-toolkit-12-6

Установка прошла успешно. Однако версия nvcc по-прежнему равна 11.5. Вот 2 пакета, которые я установил. Я думал, что установка CUDA Toolkit 12.6 заменит 11.5, но NVCC по-прежнему исходит из 11.5.

Как обновить версию nvcc до 12.6?

Вот выходные данные nvcc -V:
$ nvcc -V
