If you are running on a CPU-only machine, please use torch.load with map_location=torch.device('cpu') to map your storages to the CPU.

这个错误是因为你的代码尝试在CUDA设备上加载模型参数，但是检测到没有可用的CUDA设备。如果你在一个只有CPU的机器上运行代码，请使用`torch.load`函数的`map_location`参数将模型参数映射到CPU上。你可以尝试修改代码如下：

model.load_state_dict(torch.load(r"/home/pi/Desktop/epoch50.pkl", map_location=torch.device('cpu')))

这样就能够将模型参数加载到CPU上了。希望对你有帮助！如果还有其他问题，请随时提问。

>>> %Run 12.py Traceback (most recent call last): File "D:\Thonnyproject\12.py", line 4, in <module> from tftlcd import LCD15 ModuleNotFoundError: No module named 'tftlcd'

这个错误是由于没有找到名为 'tftlcd' 的模块导致的。请确保你已经正确安装了该模块。你可以使用以下命令来安装：

pip install tftlcd

如果你已经安装了该模块但仍然遇到此错误，请检查是否有其他版本的模块与之冲突。你可以尝试卸载和重新安装模块来解决冲突问题。

Traceback ( most recent call last ) :File " C:/python/kfc.py " , line 8

Traceback (most recent call last): File "C:/python/kfc.py", line 8

这是Python中的错误追踪信息，通常在程序出现错误时会显示。它告诉我们在哪个文件的哪一行出现了错误。

具体来说，"Traceback (most recent call last)" 表示错误追踪的开始，它告诉我们下面的信息是最近一次调用的错误。

"File "C:/python/kfc.py", line 8" 表示错误发生在文件 "C:/python/kfc.py" 的第8行。

如果你想解决这个错误，可以打开 "C:/python/kfc.py" 文件，并检查第8行的代码，看看是否有语法错误或逻辑错误。
