我假设当您说“是否可以升级映像版本而无需部署新 VM？”。你的意思是降级。
是的，可以在深度学习 VM 中降级 Tensorflow 的版本
我已经运行了以下测试，看看是否可行。
1) 按照Creating a Deep Learning VM Instance From the Google Cloud Marketplace 安装深度学习虚拟机
SSH 进入虚拟机后
2) 在交互式 python shell 中检查安装的版本
>>> import tensorflow as tf

>>> print(tf.__version__)
2.1.0
下一步是运行；
pip install --upgrade tensorflow==1.14.0
命令成功，但出现以下错误；
ERROR: scikit-image 0.15.0 requires pillow>=4.3.0, which is not installed.
ERROR: imageio 2.6.1 requires pillow, which is not installed.
ERROR: tensorflow-serving-api-gpu 1.14.0 has requirement tensorflow-gpu~=1.14.0, but you'll have tensorflow-gpu 2.1.0 which is incompatible.
ERROR: tensorflow-gpu 2.1.0 has requirement numpy<2.0,>=1.16.0, but you'll have numpy 1.15.4 which is incompatible.
ERROR: tensorflow-gpu 2.1.0 has requirement scipy==1.4.1; python_version >= "3", but you'll have scipy 1.1.0 which is incompatible.
ERROR: tensorflow-io 0.9.10 has requirement tensorflow==2.1.0rc0, but you'll have tensorflow 1.4.0 which is incompatible.
如您所见，这会导致依赖性问题。
接下来的步骤是；
a) pip install --upgrade pillow==4.3.0
b) pip install --upgrade tensorflow-gpu==1.14.0
在交互式 python shell 中再次检查版本
