importterror:在vscode中导入syft时导入lib时DLL加载失败

Question

我用conda和python 3.9.7创建了一个新的环境(my_syft env)，并安装了syft 0.5.0。

然后我检查我的模块的安装，似乎安装通过正确

C:Userstamir>conda activate my_syft_env

(my_syft_env) C:Userstamir>python
Python 3.9.7 (default, Sep 16 2021, 16:59:28) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on 
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import syft
>>>
>>> import sys
>>> print(sys.executable)
C:Userstamiranaconda3envsmy_syft_envpython.exe
>>> 

然后尝试在VScode中运行并检查我的模块，并选择当前环境C:Userstamiranaconda3envsmy_syft_envpython.exe

import syft
print("hellow")

but get en error

我不知道为什么有错误。

Answer 1

我可能来晚了，但是为了解释这个线程，您可能已经从默认的conda通道安装了libboost和boost-cpp。试试以下命令:

• conda install libboost boost-cpp -c conda-forge
• 如果在Windows机器上，确保你有Visual c++ Redistributables 2019或更高版本。
• 查看pyarrow的pip版本是否有效。

Answer 2

我在使用python 3.10的windows上遇到了同样的问题，我的解决方法如下:

1. 升级皮普:

python -m pip install——upgrade pip

2. install/upgradepyarrow:

pip install——upgrade pyarrow
