ImportError libdynet.so: 无法打开共享对象文件，没有这样的文件或目录

Question

今天我尝试运行一个简单的 dynet 程序（我运行几个月前没有问题），但出现以下错误：

Traceback (most recent call last):
  File "/home/erelsgl/Dropbox/dicta/text-taggers/test_dynet.py", line 1, in <module>
    import dynet
  File "/usr/local/lib/python3.5/dist-packages/dyNET-0.0.0-py3.5-linux-x86_64.egg/dynet.py", line 17, in <module>
    from _dynet import *
ImportError: libdynet.so: cannot open shared object file: No such file or directory

即使使用仅包含 "import dynet".

的最小程序，我也会遇到同样的错误

我尝试通过几种方式重新安装 dynet：

$ sudo pip3 install dynet
Requirement already satisfied: dynet in /usr/local/lib/python3.5/dist-packages/dyNET-0.0.0-py3.5-linux-x86_64.egg (0.0.0)
Requirement already satisfied: cython in /usr/local/lib/python3.5/dist-packages (from dynet) (0.25.2)
Requirement already satisfied: numpy in /usr/local/lib/python3.5/dist-packages (from dynet) (1.12.1)

还有：

$ sudo -H pip3 install git+https://github.com/clab/dynet#egg=dynet
Requirement already satisfied: dynet from git+https://github.com/clab/dynet#egg=dynet in /usr/local/lib/python3.5/dist-packages/dyNET-0.0.0-py3.5-linux-x86_64.egg (0.0.0)
Requirement already satisfied: cython in /usr/local/lib/python3.5/dist-packages (from dynet) (0.25.2)
Requirement already satisfied: numpy in /usr/local/lib/python3.5/dist-packages (from dynet) (1.12.1)

但是程序还是不行...我该怎么办？

编辑：这是命令行中的 python 版本：

Python 3.5.2 (default, Nov 12 2018, 13:43:14)

注意：最近我安装了 conda，所以我认为这可能是原因，但现在我已将其删除，但问题仍然存在。

您的 dynet 安装中似乎缺少已编译的共享对象文件。这可能是由于与安装或卸载其他程序有关的任何事故造成的。最好的办法是尝试卸载并重新安装 dynet，看看它是否有效。

如果这不起作用，请尝试在虚拟环境中安装 dynet。

ImportError libdynet.so: 无法打开共享对象文件，没有这样的文件或目录

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

python-import

python-3.x

dynet
