[yt-users] Problem generating python executable in yt 3.0

[Juan Camilo Ibanez Mejia]

Hi all,

well I found an previous install script for yt 3.0, about 4-5 months old, installed yt 3.0 with it and apparently it's working and scripts seem to be working as well.  Not sure what is happening with the new install script in my machine.

Best,
Juan

Hi Nathan,

the OS is Ubuntu 14.04.2.

I tried reinstalling yt3.0 but got the following error:

I tried installing setuptools in my home dir, as I don't have root access in this machine, but was unable to it kept complaining that the folder where I wanted to install this package  did not support .pth files.

Any ideas ?

Thanks for your help.
Best,
Juan

Hi all,

I'm running into some problems while trying to generate a python executable in yt3.0
I was able to do it in yt2.6 but not in this newer version, this is an example of what I'm doing:

>#!/home/jcibanezm/codes/yt30/yt-x86_64/bin/python
>
>import yt
>print "Hello World"

And when I run this, I get the following error:

Traceback (most recent call last):
  File "./Test.py", line 3, in <module>
    from yt.config import ytcfg;ytcfg["yt","__withinreason"]="True"
  File "/home/jcibanezm/codes/yt30/yt-x86_64/src/yt-hg/yt/__init__.py", line 121, in <module>

    import yt.utilities.png_writer as pw
  File "/home/jcibanezm/codes/yt30/yt-x86_64/src/yt-hg/yt/utilities/png_writer.py", line 13, in <module>
    import matplotlib._png as _png
ImportError: libpng16.so.16: cannot open shared object file: No such file or directory

It looks like your python installation is broken - matplotlib can't find libpng. Since it was able to find it when matplotlib was installed initally, this indicates to me that libpng was deleted out from under it.

What OS is this?

Have you tried completely deleting the yt-x86_64 folder and rerunning the install script?



Any idea ?
thanks for your help.
Best,
Juan
