Google Colab未使用＆＃x27; sudo＆＃x27;
我一直在使用Google Colab生产搅拌机渲染器几个月，但是今天我的脚本停止工作而没有任何更改。我使用sudo运行脚本，无论出于何种原因，Google COLAB都没有使GPU访问使用sudo运行的命令。
这是nvidia-smi的输出：
/content# nvidia-smi

但是，如果使用sudo运行，则同一命令会引发错误：
/content# sudo nvidia-smi
Failed to initialize NVML: Driver/library version mismatch
sudo对我来说很重要无论出于何种原因，命令都没有苏多（Sudo）不起作用。
/content# ./blender-3.1.0-linux-x64/blender -b --python-console -noaudio

I've been using Google Colab to produce Blender renders for a few months, but today my scripts stopped working without any changes. I run my scripts with sudo and for whatever reason Google Colab is not giving GPU access to commands run with sudo.
This is the output for nvidia-smi:
/content# nvidia-smi

But the same command throws an error if run with sudo:
/content# sudo nvidia-smi
Failed to initialize NVML: Driver/library version mismatch
sudo is important for me because my Blender commands, for whatever reason, don't work without sudo.
/content# ./blender-3.1.0-linux-x64/blender -b --python-console -noaudio
