Hi,

When I configure the Snappy package on the 64 bit Ubuntu 16.04 LTS, it failed with the following info.

Configuring SNAP-Python interface…

When I opened the snappyulil.log file, the info is

Does anyone meet this issue before? Thanks a lot.

Snappy installed on several Ubuntu 86_64 16.04 LTS systems without any problems, but we install snap separately for each user, not under a common directory in/usr/local. For example:

$ ~/snap/bin/snappy-conf /usr/bin/python2.7 Configuring SNAP-Python interface... Done. The SNAP-Python interface is located in '/home/gwhite/.snap/snap-python/snappy' When using SNAP from Python, either do: sys.path.append('/home/gwhite/.snap/snap-python') or copy the 'snappy' module into your Python's 'site-packages' directory.

If you want the snappy module in site-packages, you can do something like:

$ sudo mv ~/.snap/snap-python/snappy /usr/local/lib/python2.7/site-packages/

Did the user that ran snappy-conf have appropriate permissions to write into the site-packages directory?

Thank you for the kind reply. Yes, we have the permission to write to the site-packages.
There is a folder name snappy is generated, but once I run that an “Segmentation fault (core dumped)” is coming out.

I re-installed the snap in the folder /opt/snap, it has the same issue too. Thanks again

#4

I suspect snappy-conf is running into a problem writing something outside the target snappy directory. One candidate for the problem is the snappy-properties file. Normally, snappy-conf writes $HOME/.snap/snap-python/snappy.properties. Is this properties file being created? If you have been using sudo for SNAP installs, you may have permission issues with $HOME/.snap.

Hi, I don’t know if two late to answer. But I had the same problem as you and I have solved it using a fresh virtual environment to use with snappy. I had created using the venv using conda

  1. Create the environment to use with snappy

    conda create --name snappy python=3.5

  2. Configure python to use snap-python (using the interpreter of our virtual environment)

    ./snappy-conf ~/anaconda3/envs/snappy8/bin/python

Python and Snap
