The log and show=fetch appear to not work under python
for some reason; stdout/stderr redirect?
In any case I can duplicate the error using wget e.g.
wget
'http://ingria.coas.oregonstate.edu:80/opendap/aggregation/ocean_time_aggregation.ncml.dods'
So, since netcdf is not involved at all, the error must
be coming from the hyrax server. You will need to post
to opendap-tech@xxxxxxxxxxx to see if they can help.

If you are using the netcdf-c library (thru python)

So you might have

nice hint! but I don't see anything useful. I've enclosed the log. Maybe
someone else can make some sense of it.

I can confirm. Looks like a libdap/hyrax issue?
thanks -- does netcdf use libdap?
but anyway, which one has the bug? One would need to see if the
request
was being made correctly -- and I haqv no idea how to do that :-(

DAS seems to work just fine while DODS is returning:
...
Error {
code = -111;
message = "libdap error transmitting DataDDS: Could not
read the
variable `ntimes'.";
};

Hi all,
We're trying to use the netCDF4 python lib to access
data on an
what I thikn is a HYRAX server. It can create the
Dataset object
seemingly fine, and creates a variabel object fine --
but then
gives me:
RuntimeError: NetCDF: file not found
when I try to extract some data from the variable.
Noett hat this seems to work fien with PyDAP -- so maybe
that
means that it's a netcdf lib problem, rather than a
HYRAX problem.
But I have no idea how to debug this
I'm using a pretty recent version of the netcdf lib:
In [8]: netCDF4.getlibversion()
Out[8]: u'4.4.1 of Aug 10 2016 18:32:53 $'
though the failure is the same with older versions as
well. (and
both on Windows and OS-X so far...)
I've enclosed a small python script that demonstrates the
problem -- the problem url is in the script.
Thanks for any hints!
