当我在此处运行mnist教程时:https://www.tensorflow.org/tutorials/quickstart/beginner

我收到此错误:

我正在Unbuntu上使用TF-2。我有两个问题:1)我的Ubuntu有64G内存,而我的GPU有2G内存。当它报告错误“内存不足”时,是否是因为训练仅使用GPU的内存,而不是64G?]

2)如何解决内存不足错误?

是,训练使用GPU内存,因为您在训练时将数据输入到GPU。

问题是您使用的视频卡的视频内存很少。 2GB的VRAM不足以进行深度学习。

我建议您至少使用具有6 GB VRAM的视频卡。

如果无法切换到更好的硬件,则可以选择使用AWS(Amazon Web Services)或Google Colab来使用视频卡。
