Question

我正在尝试实现fastai预训练语言模型，这需要工作才能进行。运行代码后，我遇到了有关导入割炬的问题。_C

我通过pip在Linux python 3.7.1上运行它：火炬1.0.1.post2，CUDA V7.5.17。我收到此错误：

Traceback (most recent call last):
  File "pretrain_lm.py", line 7, in <module>
    import fastai
  File "/home/andira/anaconda3/lib/python3.7/site-packages/fastai/__init__.py", line 1, in <module>
    from .basic_train import *
  File "/home/andira/anaconda3/lib/python3.7/site-packages/fastai/basic_train.py", line 2, in <module>
    from .torch_core import *

    from .imports.torch import *
  File "/home/andira/anaconda3/lib/python3.7/site-packages/fastai/imports/__init__.py", line 2, in <module>
    from .torch import *
  File "/home/andira/anaconda3/lib/python3.7/site-packages/fastai/imports/torch.py", line 1, in <module>
    import torch, torch.nn.functional as F
  File "/home/andira/anaconda3/lib/python3.7/site-packages/torch/__init__.py", line 84, in <module>
    from torch._C import *
ImportError: libtorch_python.so: cannot open shared object file: No such file or directory

所以我尝试运行此行：

from torch._C import *

得到相同的结果

ImportError: libtorch_python.so: cannot open shared object file: No such file or directory

我检查了/home/andira/anaconda3/lib/python3.7/site-packages/torch/lib，只有libcaffe2_gpu.so和libshm.so文件，但我也找不到libtorch_python.so。我的问题是，libtorch_python.so实际上是什么？我已经阅读了一些文章，并且像大多数文章一样谈论未定义符号，而不是无法打开共享对象文件：没有像我这样的文件或目录。我是python和火炬的新手，非常感谢您的回答。

Answer 1

我的问题解决了。我两次卸载了割炬pip uninstall torch; pip uninstall torch，然后将其重新安装回了pip install torch==1.0.1.post2

错误libtorch_python.so：无法打开共享库文件：没有这样的文件或目录
