Hi, I'm trying to make a mask using a shapefile of Brazil using the examplE: http://basemaptutorial.readthedocs.io/en/latest/clip.html I run my script and I had the messages: Traceback (most recent call last): File "mascarapy2.py", line 7, in <module> from osgeo import gdal File "/home/conrado/anaconda3/lib/python2.7/site-packages/osgeo/__init__.py", line 21, in <module> _gdal = swig_import_helper() File "/home/conrado/anaconda3/lib/python2.7/site-packages/osgeo/__init__.py", line 17, in swig_import_helper _mod = imp.load_module('_gdal', fp, pathname, description) ImportError: /home/conrado/anaconda3/lib/python2.7/site-packages/osgeo/../../.././libkea.so.1.4.7: undefined symbol: _ZN2H56H5FileC1ERKSsjRKNS_17FileCreatPropListERKNS_15FileAccPropListE Please, what can I do to solve this.

testfixtures 6.0.2 released - important bug fix!
by Chris Withers May 2, 2018

May 2, 2018

Hi All, I'm afraid I've found quite a serious regression in the 6.x series of testfixtures releases: Objects that had neither __dict__ nor __slots__ would always be considered equal by compare(). I hit this comparing datetimes, but this would also affect types provides by extensions in other languages such as C or C++. This did not affect built-in types such as dict, set, tuple and list as they have specific comparers provided that were not affects. I've released 6.0.2 to fix this and would urge anyone using 6.0.0 or 6.0.1 to upgrade as soon as possible. The package is on PyPI and a full list of all the links to docs, issue trackers and the like can be found here: https://github.com/Simplistix/testfixtures Any questions, please do ask on the Testing in Python list or on the Simplistix open source mailing list... cheers, Chris

venv: make installed modules visible
by Rich Shepard May 1, 2018

May 1, 2018

Activating venv and trying to run the project Python tells me it cannot find the wxPython4 modules: Traceback (most recent call last): File "./openEDMS.py", line 12, in <module> import wx ModuleNotFoundError: No module named 'wx' I've read the Python3 venv standard library doc page (section 28.3) without seeing how to make installed modules (such as wxPython, psycopg2, and SQLAlchemy visible in the virtual environment. I suspect that EnvBuilder is involved but I'm not seeing how to apply this class ... if that's how modules are made visible in the venv. A clue is needed. Rich

Python 2.7.15 Windows MSI removes previous 2.7.x binaries?
by phennings＠gmail.com May 1, 2018

May 1, 2018

I downloaded the 64-bit Windows MSI for Python 2.7.15 and upon finishing the installation, I noted that prior Python installs had effectively been removed, only leaving a Lib and Scripts folder in the directory to which said prior version had been installed. For what it's worth, it appears this is only true if I install for 'All users' rather than for 'just this user'. I can't find anything in the release notes, docs or on this mailing list that describes the motivation for doing this. I personally find that having multiple versions installed on Windows is very helpful for being able to target distribution version for the purposes of constructing virtualenvs. Can anyone say whether this is intended behavior?

[RELEASE] Python 2.7.15
by Benjamin Peterson May 1, 2018

May 1, 2018

Greetings, I'm pleased to announce the immediate availability of Python 2.7.15, the latest bug fix release in the senescent Python 2.7 series. Source and binary downloads may be found on python.org: https://www.python.org/downloads/release/python-2715/ Bugs should be reported to https://bugs.python.org/ The source tarball contains a complete changelog in the Misc/NEWS file. The only change since the release candidate is a fix for undefined C behavior that newer compilers (including GCC 8) have started to exploit. Users of the macOS binaries should note that all python.org macOS installers now ship with a builtin copy of OpenSSL. Additionally, there is a new additional installer variant for macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6. See the installer README for more information. Happy May, Benjamin 2.7 release manager
