问题
I followed this to install conda plotly-orca on an AWS EC2 instance (built on anaconda-python3 image) but hit Cannot open shared object error when orca is invoked. The fix is to install libgtk2.0-0 and libgconf-2-4 packages which unfortunately are not available on AWS EC2 linux distribution (non ubuntu). So I downloaded this standalone orca-1.3.1.AppImage for linux.
I use --appimage-extract to extract orca-1.3.1.AppImage to /home/ec2-user/squashfs-root folder and run:
xvfb-run --auto-servernum --server-args "-screen 0 640x480x24" /home/ec2-user/squashfs-root/orca "$@" > /opt/conda/envs/pysig/bin/orca
chmod 777 /opt/conda/envs/pysig/bin/orca
However orca --help returns this:
/opt/conda/envs/pysig/bin/orca: line 1: /home/ec2-user/squashfs-root/orca:: No such file or directory
But orca does exist in my /home/ec2-user/squashfs-root folder:
ls -l /home/ec2-user/squashfs-root/orca
-rwxrwxrwx 1 ec2-user ec2-user 112481216 Jun 29 01:39 /home/ec2-user/squashfs-root/orca
On the ec2, I have installed Xvfb using sudo, except libgtk2.0-0 and libgconf-2-4 packages which are not available in AWS linux distribution.
I run all commands as ec2-user instead of root, because the ec2 is based on anaconda-python3 image, which assigns ec2 as the owner of all the conda stuff.
Any idea why orca --help cant find /home/ec2-user/squashfs-root/orca when it does exist in /home/ec2-user/squashfs-root folder which I have already applied chmod -R 777 over it?
All the examples I can find on the web for orca on linux have been on ubuntu distribution only, but on github, Tests and Linux builds are marked as PASSED. There is zero response from the plotly orca and github communities for the same question asked. The whole experience has been so clunky and painful, time to look into orca alternative?
