ARCSI1.0.0 on anaconda python 2.7 problem on converting LS8 to SR

[Abhishes Lamsal]

Hi,

I am using Linux 16.04 with anaconda python 2.7 installed. 

I installed ARCSI using "python setup.py install" by downloading files from bitbucket. (Reason I did this way is because following command "conda create -n arcsi -c au-eoed -c conda-forge arcsi"  didn't work)

Now when I am using arcsi to convert LS8 to SR I am getting following error. Here is the detail console output. 

arcsi.py -s ls8 -f KEA --stats -p RAD -o ./ -i LC80270332016348LGN00/LC80270332016348LGN00_MTL.txt

Hi,

The development builds of ARCSI and RSGISLib (from the au-eoed channel) are only built using Python 3.5. Try setting Python 3.5 for that environment using:

conda create -n arcsi -c au-eoed -c conda-forge arcsi python=3.5

Thanks,

Dan

Does this mean, there is no way we can make it work on python 2.7 ?

Yes, ARCSI supports Python 2.7 but until the next release is built (which will made available in the rios channel) binaries for RSGISLib will only be available for Python 3.5.

If you need development builds for Python 2.7 you can try building yourself, the conda recipes are available from: https://bitbucket.org/petebunting/conda-recipes

Hope this helps,

Dan

Thank you for giving some hope. I am quite new on this so its a request, if there is any documentation or anything to help me on building ? 

Initially, I downloaded ARCSI source from bitbucket and install it via python setup.py install. 

It seems like installed it but it didnt do the job. Got the error message as I mentioned in first thread. 

Thank you

Hi,

Did you try installing the Python 3.5 build as I suggested?

My recommendation would be to install the Python 3 version and then, if you need it, change to Python 2.7 when the binaries are made for the next release. This should be in the next month or so, Pete has made a lot of changes, including adding Sentinel 2 support to ARCSI so we’ve been holding off creating a release until these were finished.

If you need to get it working under Python 2.7, first question is how did you install all the pre-requsites for ARCSI? Specifically how did you install RSGISLib and what version are you using?

Thanks,

Dan
