ImportError: DLL load failed while importing lib with importing syft in vscode

Question

I create a new environment (my_syft env) with conda and python 3.9.7 and install syft 0.5.0.

Then I check the installation of my module and it's seem that the installations pass correctly

C:\Users\tamir>conda activate my_syft_env
        
(my_syft_env) C:\Users\tamir>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:\Users\tamir\anaconda3\envs\my_syft_env\python.exe
>>> 

Then in try to run and check my module in VScode and choose the current environment C:\Users\tamir\anaconda3\envs\my_syft_env\python.exe

import syft
print("hellow")

but get en error

ImportError: DLL load failed while importing lib: The specified procedure could not be found.

I dont know why there is an error.

Answer 1

I may be late, but to paraphrase this thread, you might have installed libboost and boost-cpp from the default conda channels. Try the following:

• conda install libboost boost-cpp -c conda-forge
• If on a Windows machine, make sure you have Visual C++ Redistributables 2019 or later.
• See if the pip version of pyarrow works.

Answer 2

I had the same problem, on windows with python 3.10, and which I solved as follows:

1. upgrade pip:

python -m pip install --upgrade pip

2. install/upgrade pyarrow:

pip install --upgrade pyarrow
