Hello.

I am running this statement
modis_GEO.py A2018108105738.L1A_LAC

and I get this error:

Exception: [Errno 101] Network is unreachable
Exception: 'NoneType' object has no attribute 'status'

I ran this statement to

python simple_python_connection_test.py

and I got this output:

read https://oceancolor.gsfc.nasa.gov/ successfully

Funny enough, it was working yesterday in the same computer but for some reason, it completely stopped working and hasn't worked ever since. I even shifted processing to another computer and I got this error.

Error! could not establish a network connection. Check your network connection.
If you do not find a problem, please try again later.

Would you help me narrow what the problem might be?

James,

How did you install the OCSSW package?
While the path suggests you have v7.4, the error belies this.  You have v7.5 of the OCSSW code installed.  We've been putting that out for while entirely unsupported as it's so we can test it before releasing.  Did you intend to install v7.5?

Hello Sean.

I installed it as

./install_ocssw.py --install-dir=$HOME/ocssw --direct-broadcast --aqua --terra --npp

I followed the instructions from here  https://seadas.gsfc.nasa.gov/downloads/ 

Well, I intended to install the most up to date and stable SeaDAS.

Kind regards,
James

Ah, I see.  We left off the --git-branch=<version> bit for the --direct-broadcast example...
Without it you get the most recent version, but since we're close to releasing the NEXT version, you got that one...which apparently wasn't yet stable :eek:

On Friday, some updates to v7.5 went in, so you probably can keep it - just rerun the command to get the updates:
./install_ocssw.py --install-dir=$HOME/ocssw --direct-broadcast --aqua --terra --npp --git-branch=v7.5

The problem you had should be resolved if you do so.  If it persists, well you can reinstall with v7.4, but you'll want to include --clean.
...and let us know.  I was hoping the updates made on Friday would be the releasable version.
