这个错误提示是因为您传递给torch.onnx.export函数的model参数是一个字符串而不是模型对象。请确保您已经正确加载了模型,并将其传递给export函数。
例如,如果您的PyTorch模型保存在名为"model.pth"的文件中,您可以使用以下代码加载模型并将其导出为ONNX格式:
```
import torch
# 加载PyTorch模型
model = torch.load("model.pth")
# 创建一个随机输入张量
dummy_input = torch.randn(1, 3, 224, 224)
# 导出模型为ONNX格式
output_file = "model.onnx"
torch.onnx.export(model, dummy_input, output_file, verbose=False)
```
请注意,这里的model参数是一个模型对象,它是使用torch.load函数从文件中加载的。如果您使用不同的方法加载模型,请确保将正确的模型对象传递给export函数。

这个错误提示是在运行 PyTorch 目标检测的 Faster R-CNN 模型时出现的。根据错误提示,似乎是在加载 `caffe2_detectron_ops_gpu.dll` 或其某个依赖项时出现了问题。
可能的原因和解决方法如下:
1. 内存不足:错误提示中提到“页面文件太小”,这可能是因为内存不足导致的。可以尝试关闭一些占用内存较多的程序或者增加内存。
2. 文件损坏:`caffe2_detectron_ops_gpu.dll` 文件或其某个依赖项可能被损坏了,需要重新安装 PyTorch。
3. 缺失依赖项:该文件可能依赖于其他一些文件,而这些文件可能缺失或损坏了。可以尝试重新安装 PyTorch 或者查找缺失的文件并手动安装。
4. 不兼容的操作系统:该文件可能不兼容当前操作系统。可以尝试更新操作系统或者查找适用于当前操作系统的版本。
希望以上方法能够帮助您解决问题。
