[pymvpa] PyMVPA WARNING messages

[Salim Al-wasity]

DearsI am quite new user of PyMVPA package and I have some warning messages:
1- When I use (from mvpa2.suite import *) I get this:
Warning (from warnings module):  File "C:\Python27\lib\site-packages\numpy\lib\utils.py", line 99    warnings.warn(depdoc, DeprecationWarning)DeprecationWarning: `scipy.weave` is deprecated, use `weave` instead!
Warning (from warnings module):  File "C:\Python27\lib\site-packages\scipy\integrate\quadpack.py", line 352    warnings.warn(msg, IntegrationWarning)IntegrationWarning: Extremely bad integrand behavior occurs at some points of the  integration interval.

2- When I train a classifier using a searchlight results:clf=LinearCSVMC()cv = CrossValidation(clf, NFoldPartitioner())sl = sphere_searchlight(cv, radius=3, postproc=mean_sample())sel=FractionTailSelector(0.005, mode='select', tail='lower')
new_ds=ds[:,sel(res)]
cvte=CrossValidation(clf, NFoldPartitioner(), enable_ca=['stats'])results = cvte(new_ds) ###print np.round(cvte.ca.stats.stats['ACC%'], 1)I get this error when I execute the last (print ) command:
Warning (from warnings module):  File "C:\Python27\lib\site-packages\numpy\lib\utils.py", line 99    warnings.warn(depdoc, DeprecationWarning)DeprecationWarning: `nanmean` is deprecated!scipy.stats.nanmean is deprecated in scipy 0.15.0 in favour of numpy.nanmean.
3- When I use (evds = fit_event_hrf_model(ds,events,time_attr='time_coords',condition_attr=('targets', 'chunks'))) I get this:
Warning (from warnings module):  File "C:\Python27\lib\site-packages\nipy\modalities\fmri\design_matrix.py", line 229    warn('Matrix is singular at working precision, regularizing...')UserWarning: Matrix is singular at working precision, regularizing...
