cdms2.setAutoBounds('off') problem (OK with 'on')

[jypeter]

@dnadeau4 and @doutriaux1 I'm using 2.8.0 and if I run the script at the end of this issue with the setAutoBounds line commented out, it works fine. But when the line is not commented, I get the following exception:

If I specify 'on' instead of 'off', it works fine as well...

Can you check what's wrong? Thanks!

hum... the default is 2 which means no autobounds except for lat/lon

[dnadeau4]

@jypeter netcdf4 is normal by default, you need to set netcdf3 flags. cdms2.setNetcdf4Flag`

https://github.com/UV-CDAT/cdms/blob/master/Lib/dataset.py#L183

For the autobounds, this seems to be a numpy 1.11 error after the upgrade.
