dictlearn's Issues

Issue when importing dictlearn

Hi, I encountered the following error when importing dictlearn. I have tried to reinstall the package with
python setup.py install and python setup.py build_ext but still gives an error.

import dictlearn
Traceback (most recent call last):

  File "/home/david/dictlearn/src/dictlearn/dictlearn/__init__.py", line 84, in <module>
    ___SETUP___

NameError: name '___SETUP___' is not defined


During handling of the above exception, another exception occurred:

Cannot import dictlearn

When i attempt to import dictlearn using python 2.7 I get the following error:

Any advice you can give for resolving this issue would be greatly appreciated.

Thanks

Issue with install on Mac OS X

I tried to install the module via the two lines of code below:

$ pip install -r requirements.txt
$ python setup.py install

but got the following error after the second line (running setup.py install):

...

clang: error: unsupported option '-fopenmp'

Any suggestions? I am looking to find a module or open-sourced implementation of a sparse dictionary learning algorithm, and yours looks great--I'd love use it.

Issue when importing dictlearn?

Hi, I encountered the following error when importing dictlearn. I have tried to reinstall the package in setup.py but still not working.

Tutorial on dl.ksvd has incorrect syntax

I am having trouble with dl.ksvd, using the tutorial code below (trying to train on my own image - 'image_rescaled'). Here is my code:

1. image_patches = dl.Patches(image_rescaled.astype(float), 8)
2. dictionary_a = dl.dct_dict(256, 8)
3. dictionary_b = dl.ksvd(image_patches, dictionary_a, 1, n_nonzero=8, n_threads=4, verbose=True)
4. dl.visualize_dictionary(dictionary_b, 16, 16)

And the error:
AttributeError: 'tuple' object has no attribute 'shape'

The problem occurs when I try visualize_dictionary, but changing line 4 to:
dl.visualize_dictionary(dictionary_b[0], 16, 16)
solves this problem. The code looks fine but the tutorial is a bit misleading - since dictionary_a is not the same as dictionary_b (dictionary_b is a tuple).
