Miscellaneous deprecation warnings in rasterio, scikit-learn

[grovduck]

I'm finding a few warnings in some required packages using these versions:

pyimpute==0.1.2
scikit-learn==0.19.1
rasterio==1.0a12

pyimpute/src/pyimpute/_main.py

Line 8 in 58706f4

from sklearn import cross_validation

DeprecationWarning: This module was deprecated in version 0.18 in favor of the
model_selection module into which all the refactored classes and functions are
moved. Also note that the interface of the new CV iterators are different from that of
this module. This module will be removed in 0.20.

Lines 109 to 113 in 58706f4

	# Save or check the geotransform
	if not aff:
	aff = src.affine
	else:
	assert aff == src.affine

RasterioDeprecationWarning: 'src.affine' is deprecated.  Please switch to
'src.transform'. See https://github.com/mapbox/rasterio/issues/86 for details

pyimpute/src/pyimpute/_main.py

Lines 161 to 177 in 58706f4

	profile = {
	'affine': raster_info['affine'],
	'blockxsize': shape[1],
	'height': shape[0],
	'blockysize': 1,
	'count': 1,
	'crs': raster_info['crs'],
	'driver': u'GTiff',
	'dtype': 'int16',
	'nodata': -32768,
	'tiled': False,
	'transform': raster_info['affine'].to_gdal(),
	'width': shape[1]}
	try:
	response_path = os.path.join(outdir, "responses.tif")
	response_ds = rasterio.open(response_path, 'w', **profile)

UserWarning: Found both 'affine' and 'transform' in rasterio.open() - choosing 'transform'

This last one also causes an UnboundLocalError in the finally block at line 232 because response_ds didn't get opened properly?

The first two didn't cause any issues. For the last one, I commented out the affine key in the profile dictionary and made transform equal to raster_info['affine'].
