pip install syft - ZSTD errors

[phillipeloher]

Received lots of ZSTD errors on OSX Mac Sierra when installing 'pip install syft' within Anaconda. Tried the various workarounds in documentation and also tried installing from source - still had the same errors.

Running 'conda install gcc' fixed the issue for me. Which changed GCC in my conda environment from:

gcc --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 9.0.0 (clang-900.0.39.2)
Target: x86_64-apple-darwin16.7.0
Thread model: posix

To:
gcc --version
gcc (GCC) 4.8.5

Perhaps add this work-around to documentation if it will help others.

Thanks for the indication!

[phillipeloher]

Thank you. I did see/try the 'pip install --upgrade --force-reinstall zstd' command, but it failed with similar ZSTD errors which led me to another work-around. Just wanted to mention incase others benefit from it.

I just bumped into a lot of error with zstd on an Ubuntu 16.04 machine a few hours ago. They were solved by running:

sudo apt-get install python3.6-dev

I share also here the install procedure I use on Google colab, which is not very clean but works for people wanting to use the last updates from dev branch (and their amazing bugs!)

!pip install tf-encrypted

! URL="https://github.com/openmined/PySyft.git" && FOLDER="PySyft" && if [ ! -d $FOLDER ]; then git clone -b dev --single-branch $URL; else (cd $FOLDER && git pull $URL && cd ..); fi;

!cd PySyft; python setup.py install  > /dev/null

import os
import sys
module_path = os.path.abspath(os.path.join('./PySyft'))
if module_path not in sys.path:
    sys.path.append(module_path)

!pip install --upgrade --force-reinstall lz4
!pip install --upgrade --force-reinstall websocket
!pip install --upgrade --force-reinstall websockets
!pip install --upgrade --force-reinstall zstd

Hi I tried to install pysyft on OSX Mac Mojave and have an installation error regarding zstd

The solution that worked for me on MacOS Mojave 10.14.5:

conda create -n py3_6_3 python=3.6.3 anaconda
conda activate py3_6_3
conda install pytorch torchvision -c pytorch
pip install --upgrade --force-reinstall zstd
pip install syft

Hey @dvu4

I'm facing the exactly similar issue on MacOS Mojave Ver 10.14.5. Were you able to find a solution to this issue?

Conda Version: 4.6.14
Python Version in Conda environment: python 3.7.3

Can anyone else with a similar configuration please help me with the installation?

I just bumped into a lot of error with zstd on an Ubuntu 16.04 machine a few hours ago. They were solved by running:

sudo apt-get install python3.6-dev
@DanyEle How can you do that successfully? I am on the Ubuntu16.04 too and I get the error that the zstd cannot be imported. And when I do as your guide I get the following error:

(pysyft) daisy@ubuntu:~/PySyft$ sudo apt-get install python3.6-dev
Reading package lists... Done

I solved this issue by following the instructions on this page: https://discourse.mc-stan.org/t/compilation-error-in-pystan-macos-mojave/6383/3 .
I installed the package using:
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /.

This was also solved by changing the gcc version to a more recent one using:
export CC=/usr/local/Cellar/gcc/9.2.0/bin/gcc-9
export CFLAGS="-Wa,-q"
and then running:
pip install --upgrade --force-reinstall zstd

This issue happened again on macOS Catalina and all the solutions above cannot fix it.
Same error message as above.
