STL-10 scripts out-of-date and downsampling

[Laurent Dinh]

Hi, 

The scripts in the pylearn2/scripts/datasets/ associated with STL-10 seem to import the wrong module "string" instead of "string_utils". 

Moreover the downsampling script for STL-10 seems to be not working. The error I get is in the attached file. 

For additional information, I run on anaconda and when I replace the in pylearn2/datasets/preprocessing.py file the Conv3D.conv3D op used in the Downsample Preprocessor with Conv2D.conv2d things seem to work (given a few theano.tensor.dimshuffle and numpy.transpose inserted). 

Cheers,

Thanks for the bug report. I fixed the string_utils thing, haven't had
time to look into the rest yet. You have everything working how you
need it though, right?

Hi Laurent,

The error message below seems to boil down to:
> /usr/bin/ld: cannot find -lmkl_gnu_thread
> collect2: error: ld returned 1 exit status

Did you specify a value for blas.ldflags in your .theanorc or
THEANO_FLAGS? If that's the case, you may need to also provide the
relevant '-L' flag indicating where libmkl_gnu_thread.so is.
