问题：
近期在Windows 10 Pro 64位系统下，想基于Pytorch GPU版本进行时间序列LSTM模型的训练，机器配置为数年前的硬件，显卡是Nvidia GeForce GT730，CUDA版本是11.4， 如下所示：
在安装了Nvidia Windows相关驱动及CUDA工具包之后，根据官方推荐，进行了如下安装：
Previous PyTorch Versions | PyTorch
# CUDA 11.3
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu113成功安装后，显示版本已具备CUDA功能，如下：
但在将程序调整为GPU相关的支持后，当运行时会提示下面的警告：
显示GT 730是较旧版本，具备CUDA Capability 3.5， 而Pytorch版本目前支持 Capability 3.7以上的效能，因而可以断定该Pytorch GPU能力无法在GT 730的CUDA上发挥。
这点判断可以从以下命令行可以直观看到：
从网络多种资源（包括官方支持), 得到的信息是Pytorch 1.5以前的版本（有说 1.3.1) 才提供Capabilities 3.5的内置支持。
可能解决办法：
可以参考以下链接，Pytorch技术人员提供了当前版本Pytorch能够支持GT730 3.5 CUDA Capability的方法：
PyTorch for Tesla k40c with cuda 11.2 - #4 by ptrblck - PyTorch Forums
为使最新版本具备支持GT 730 CUDA的能力，需要按照其中的建议进行编译：
https://github.com/pytorch/pytorch#from-source
鉴于Tensorflow版本可以发挥GPU能力，本人对上述方案尚未实际尝试，仅供参考。
Pytorch CUDA Compute Capability各版本支持情况
有高手将Pytorch各官方版本的CUDA Capability支持情况用Python脚本进行了分析汇总，可以参见以下链接：
GitHub - moi90/pytorch_compute_capabilities
https://github.com/moi90/pytorch_compute_capabilities/blob/main/table.md
截止2022年10月底的列表如下， Appreciate MOI90's smart work again!
其中相关讨论有时间也可以参考：
