How do you do imports in python 3.4, I am still a total noob in python 3 : )

[mikecroucher]

You want fixes pushed to devel?

Either direct push (to devel) or through pull requests. Master gets only updated, when I have looked at the crosscompiler (#250).

[lawrennd]

I think Max deserves some form of (at least partial) immunity from the
Python 3 "swear box" ... it's unfair to apply it strictly to someone who
spent so long in "the merchant navy". But rest of us should have to chip in.

Hints on migrating pylab to matplotlib from a novice to python(2.7 or 3.4) on conda 3.17:

-some guidelines on good syntax can be found here: https://github.com/jrjohansson/scientific-python-lectures/blob/master/Lecture-4-Matplotlib.ipynb https://github.com/jrjohansson/scientific-python-lectures/blob/master/Lecture-4-Matplotlib.ipynb

•      “from pylab import *” or “ from pylab import as pb” are replaced by the THREE lines: 
  

o Import matplotlib

o Import matplotlib.pyplot as plt

o Import numpy as np

•      The syntax of the plot is modified to include “plt” instead of “pb” and
  

•      “np” should be inserted in the math statements
  

•      The complete folder and sub-folders of “GPy.plotting” should be converted along these lines
  

Hope this helps someone to take charge of updating GPy and notebook.

I think I fixed this on the devel branch. Can someone double check please?

[finmod]

I have systematically checked the notebooks for conformity with:

%matplotlib inline

Import matplotlib

Import matplotlib.pyplot as plt

Import numpy as np

All the notebooks of GPy run smoothly after the usual print (m) and coherence of pb into plt with the exception of magnificationFactor.ipynb and sampling.ipynb

In magnification Factor at:

fig, axes = plt.subplots(1, 2, figsize=(15,5))

v1 = m_gplvm.plot_latent(labels=labels, ax=axes[0], updates=False, resolution=100)

axes[0].set_title('Latent Space')

v2 = m_gplvm.plot_magnification(labels=labels, ax=axes[1], updates=False)

axes[1].set_title('Magnification')

produces this error:

Great I am doing the refactoring right now.

Please have a look into the branch: plot_density

It is still work in progress, but I expect it to be done tonight or tomorrow.

It will also support multiple plotting libraries, which was the plan of the plotting module all along. If you don’t do everything yourself, no-one does ; )

On installing plot_density, I get the following error.

I am also having this issue and can reproduce the error messages mzwiessele posted above.

[mzwiessele]

We have a patch waiting in the branch plot_density!

If you guys can check that out again, that would be great!

There is still work left to do, but basic plotting works for matplotlib and plotting (see config file)

Max,

As before in Python 3.4, plot_density does not install properly because pandoc pypandoc dependencies do not install correctly.

[mzwiessele]

pandoc is not a dependency. It is only for generating the pypi rst readme.

It seems, that the exception occurs in f.read(), while reading the readme. there is unicode characters in the readme, that is why it breaks down.

I have written a patch using the codecs module, maybe that knows how to handle windows.

Can you try it again?

[mzwiessele]

Sry merge issues, the patch is now out.

[finmod]

Almost there.

Just fixed that one as well : )

[mzwiessele]

This I have never ever seen before. Have you got the newest version of numpy?

In order to use the c libraries you will also need a compiler (e.g. mingw or visual) for this branch, as there are no build distros of this yet (it is in development :)

[mzwiessele]

When using conda try

conda update numpy

Does that update?

[mzwiessele]

It does run on travis and on my local machine.

So now it is windows related problems, and I do not have a windows machine at ease : (

We gonna have to find a solution for this together, I'm afraid.

[finmod]

This is always the latest version.

My config is:

Software Version

Python 3.4.3 64bit [MSC v.1600 64 bit (AMD64)]

IPython 4.0.0

OS Windows 8 6.2.9200

numpy 1.9.3

scipy 0.16.0

matplotlib 1.4.3

sympy 0.7.6.1

quantecon 0.2.2

GPy 0.8.8

climin pre-0.1

version_information 1.0.3

If this works to your satisfaction on travis and your local machine, can you pls merge with devel branch as the matplotlib issue can be considered solved.

The issue on windows and the possible use of c compiler will have to wait a few more days. Visual Studio, c and f compilers have been a nightmare on windows for years. However, there is light at the end of the tunnel: Continuum Anaconda will be releasing shortly Anaconda 2.4 with Python 3.5 as standard. In turn py3.5 meshes smoothly with Visual Studio Community 2015 as reported here: http://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/ http://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/ This would make windows finally comparable to linux in terms of efficiency.

Another route is to wean GPy master and GPy devel from cython and move to numba and numbaPro. The demo notebooks on this score appear to favour the use of numba and jit instead of the cython approach.

Thank you.

Numba is still too unstable to be used in library code (features coming in and out, bugs... require keeping up with conda's development), and requires a specific version of LLVM, which means you are practically tied to Conda..

[mzwiessele]

Fixed by #262.
