我买了一台配备 GPU RTX 3050 移动版的游戏笔记本电脑。由于我想用它进行机器学习和深度学习,所以我想确保我能正确访问它的显卡。
到目前为止,我已经尝试过:
ubuntu-drivers devices
进而 :
sudo ubuntu-drivers autoinstall
它给了我这个错误:
Traceback (most recent call last):

答案1
我也遇到了同样的问题。我的解决方案是编辑detect.py命令
sudo gedit /usr/lib/python3/dist-packages/UbuntuDrivers/detect.py
然后滚动到第 835 行。
将该行代码更改为
version = int(package_name.split('-')[-2])
保存并关闭文件。您可能还需要重新启动。
显然,这是一个错误,因为有些驱动程序以单词而不是整数结尾。例如:driver-name-525-open。此代码调整采用 525 整数值。
