Hi,

I was trying to install the data processors on SeaDAS 7.5.1 and encountered the following error message:

execution exception: java.io.IOException: install_ocssw.py failed with exit code 1.
Check log for more details.

This is the same computer related to another forum post found here:

It seems that the Mac we're working on does not trust the server certificate but I haven't been able to determine how to allow access. Any suggestions? Thanks so much for the help!

You will have to run install_ocssw.py from the command line. 
- grab https://oceandata.sci.gsfc.nasa.gov/ocssw/install_ocssw.py and put it in you SEADAS directory
- edit line line 43 of install_ocssw.py
    from
downloadCommand = 'wget --tries=5 --wait=5 '
    to
downloadCommand = 'wget --no-check-certificate --tries=5 --wait=5 '

- save the file and try running it

Thanks Don!

I have 'install_ocssw.py' in the ocssw folder of the SeaDAS directory. I've tried navigating into that folder and running in Terminal with the appropriate changes made to line 43, using the command

./install_ocssw.py

I get back

./install_ocssw.py: Permission denied

I'm not the most savvy when it comes to using Terminal - am I doing something wrong?

Thanks!
Brice

You need to make the script executable.  In the terminal, go the seadas directory and run this:

chmod +x install_ocssw.py
./install_ocssw.py -i ocssw -b v7.5 --aqua

Thanks Don, works like a charm!

Hello,
I have installed seadas-7.5.1 in mac book. After, I try to install ocssw.
Unfortunately, I get a message saying that "Unable to establish an SSL connection"

How can I fix this problem? Please reply me.

Renosh

The issue is with the SSL library used by the Apple-installed version of python.
You will need to install an alternate python version (but still v2.7 - v3.x is not yet fully supported by SeaDAS).
You might try Anaconda

Hi Sean,

I tried Anaconda. Still, it is not working.

See the python version.
renosh-mb:~ highroc$ python -V
Python 2.7.15 :: Anaconda, Inc.

I think an old inbuilt version of python there in my MacBook. I don't know how to remove it.

Renosh

Try manually installing the OCSSW components:

A follow-up...I managed to get my hands on a "clean" Mac (fresh install of 10.13) and using this machine (once I installed XCode to get the git binary) I was successful installing SeaDAS and the OCSSW package using the GUI with no issues...

Can you let me know what macOS your machine is running?
