Traits WARNING, DEPRECATED: traits.has_traits.wrapped_class

[xaverm]

Executing this snippet

%pylab inline
from mayavi import mlab as ml

as the very 1st in an ipython notebook produces this:

WARNING:traits.has_traits:DEPRECATED: traits.has_traits.wrapped_class, 'the 'implements' class advisor has been deprecated. Use the 'provides' class decorator.

This occurred after an upgrade of my systems IPython from a 1.x version to a 2.x version.

IPython 2.2.0
ETS fresh pull & compile as of Sun Sep 21 10:06:27 CEST 2014

Comments / suggestions / help would be most welcome.

Are there still any devs. around monitoring this forum?
Some help on the preceding issue #143 would be very kind.

The implements feature in traits has been deprecated and replaced with a provides decorator. This is just a deprecation warning, nothing to worry about.

[dmsurti]

Closing as this is just a deprecation warning.

[mdickinson]

@dmsurti: We should still upgrade the use of the deprecated code, wherever that is. Is there an issue open on the appropriate repository?

[pberkes]

@dmsurti: I think the issue should be re-opened and fixed: even if it's just a warning, it is going to be printed out to the terminal for all application that depend on it

[itziakos]

I agree.

[ambiorix21]

I am curious if there are any solutions yet. Anyone knows?

[stefanoborini]

This appears to be fixed. Cannot reproduce it in recent versions. Closing

I get this message when using mayavi 4.4.0 - 4.4.4 with anaconda in an iPython notebook. Steps to reproduce:

• install Anaconda with python 2.7 on Mac OS X (10.11.5)
• install mayavi 4.4.0 via conda install mayavi or mayavi 4.4.4 via pip install mayavi
• export QT_API=pyqt
• ipython notebook
• in first ipython notebook cell: %gui qt
• in second ipython notebook cell: from mayavi import mlab

gives message: "WARNING:traits.has_traits:DEPRECATED: traits.has_traits.wrapped_class, 'the 'implements' class advisor has been deprecated. Use the 'provides' class decorator."

(In this setup, the python kernel crashes if I ever open the "Configure the scene" dialog box for a mayavi graphic and then click OK, but I assume that is a different problem.)

Reopening after new report.
