PyTorch - RuntimeError: [enforce fail at inline_container.cc:209] . file not found: archive/data.pkl

问题

我正在尝试使用PyTorch加载一个文件,但错误显示archive/data.pkl不存在。

代码

import torch
cachefile = 'cacheddata.pth'
torch.load(cachefile)

输出

---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)
 in 
      1 import torch
      2 cachefile = 'cacheddata.pth'
----> 3 torch.load(cachefile)

    582                     opened_file.seek(orig_position)
    583                     return torch.jit.load(opened_file)
--> 584                 return _load(opened_zipfile, map_location, pickle_module, **pickle_load_args)
    585         return _legacy_load(opened_file, map_location, pickle_module, **pickle_load_args)

    838     # Load the data (which may in turn use `persistent_load` to load tensors)
--> 839     data_file = io.BytesIO(zip_file.get_record('data.pkl'))
    840     unpickler = pickle_module.Unpickler(data_file, **pickle_load_args)
    841     unpickler.persistent_load = persistent_load
RuntimeError: [enforce fail at inline_container.cc:209] . 文件未找到:archive/data.pkl

假设

我猜测这与pickle有关,参考文档

这种保存/加载过程使用最直观的语法,需要的代码最少。以这种方式保存模型将使用Python的pickle模块保存整个模块。这种方法的缺点是序列化的数据与特定的类和保存模型时使用的确切目录结构绑定在一起。这样做的原因是pickle不保存模型类本身。相反,它保存一个指向包含类的文件的路径,在加载时使用。因此,当在其他项目中使用或进行重构后,代码可能以各种方式中断。
