Useful conda recipes for Pyomo and dependencies.

pyomo-recipes

Useful conda recipes for Pyomo and dependencies.

Installation from conda packages

All the packages are uploaded to https://anaconda.org/cachemeorg/. To install everything:

conda install pyomo pyomo.extras pyomo.solvers --channel cachemeorg

Compilation from the recipes

To compile pyomo:

$ conda build pyutilib serpent pyro4 pyomo --python 3.5

To compile pyomo.extras:

conda build suds-jurko setproctitle openopt funcdesigner derapproximator pyomo.extras --python 3.5

To compile optional solvers:

conda build glpk --python 3.5
conda build ipopt_bin --python 3.5

pyomo-recipes's Issues

Patch openopt

There are some Python 2 failures, it would be nice to have that sorted before it bytes. It might be necessary to use 2to3.

Upload packages from AppVeyor

Once everything works this should remove the need to locally compile the packages. It would be nice to increment the build number using APPVEYOR_BUILD_NUMBER and templated meta.yml files, see http://conda.pydata.org/docs/building/environment-vars.html?highlight=template#git-environment-variables.

Installing Pyomo Windows10

I am trying to install pyomo in Windows 10. My steps are:

Install Anaconda 2.7
Install Pyomo: conda install -c conda-forge pyomo
Install ipopt: conda install ipopt_bin --channel cachemeorg
But I am having the next error:

_Exception in thread Thread-6:
Traceback (most recent call last):
File "C:\Users\MC\Anaconda2\lib\threading.py", line 801, in __bootstrap_inner

The program is working well from the terminal, but from spyder I get the error above. any idea?

Add support for Python2.7

Some packages, like Gurobi, only support Python 2.7. Can we automate the creation of packages for Python 2.7?

Add ipopt package

I need @franktoffel to tell me what binaries to put there exactly.

Pyro4 dependency

In Pyomo, we treat Pyro4 as an optional dependency that is installed with pyomo.extras, but in CAChemE it is treated as a required dependency for the pyomo package.

I'd like to understand this difference. We treat Pyro4 as an optional dependency since core Pyomo functionality doesn't depend on this package. Additionally, the installation of Pyro (and the other optional dependencies) has proven fragile using PyPI. For example, PyYAML and suds-jurko installations have failed due to external dependencies on their PyPI sites.

But perhaps things are different using conda, and it may make sense to install all/most of pyomo.extras as dependencies when Pyomo is installed with conda.

Add the rest of operative systems

Use two out of three: CircleCI, Travis CI, Anaconda. Providing Linux and OS X is important too.

Windows 10 & Pyomo 4.2.10784 & Gurobi 6.5.1: Solver returns 'None' values

Hi everybody,

I had a weird error with your recipe on two Windows 10 X64 EDU installations:

Gurobi returns [None, None, ...] for the decision variables wheras other solvers e.g. "glpk" work fine. Gurobi itself is licensed and all Gurobi API examples are working. To the solver itself should be fine.

I reported and solved the problem here: https://groups.google.com/forum/#!topic/pyomo-forum/KrTMryO69f8

Short form: Installing the newest version (4.3.11388) via pip solved the problem for me.

Are you planning to provide the newest version in your recipe?

This would fix the error and using you recipe is more convenient than going the manual way.

Cheers
Cord

Error using NEOS

After installing pyomo.extras, pyomo is able to connect succesfully with NEOS Server. However, a PermissionError stops the process (only occurs in windows machines).

See https://groups.google.com/forum/#!topic/pyomo-forum/HDSHYa3RDcI

GLPK

The current recipe does not include the GLPK binaries in the system path:

[pyomo35] C:\Users\franz\Documents\GitHub\pyomo-instalacion\test_example\LP>pyomo solve --solver=glpk diet1.py diet.dat
[    0.00] Setting up Pyomo environment

[    0.07] Pyomo Finished

Solution is to install GLPK with the following anaconda package:
https://anaconda.org/snorfalorpagus/glpk

conda install -c https://conda.anaconda.org/snorfalorpagus glpk

Pyomo en Windows10 ¿error encode?

Hola Juanlu,

Vuelvo a tener el mismo problema que te comenté hace unos meses. He instalado Pyomo en Windows10. Mi problema es que al optimizar un programita (que sé que tiene solución óptima porque en otro orde funciona correctamente) me encuentro con que:

• Desde el command prompt encuentra solución óptima.
• Desde spyder me salta el siguiente error:
  En la consola de ipython me sale:

Solver log file: 'C:\Users\MC\AppData\Local\Temp\tmpf9gmk_cs_ipopt.log'

Solver problem files: ('C:\\Users\\MC\\AppData\\Local\\Temp\\tmpm1p5q1iq.pyomo.nl',)

glpk solver not working

Hi everybody,

we have used your recipe to install Python, Pyomo and solvers in a university course and everything worked fine on all operating systems.

Now I have changed my own OS to Xubuntu 16.04 64 Bit and installed all packages on the newest Anaconda version via:

conda install pyomo pyomo.extras ipopt_bin glpk --channel cachemeorg

But now somehow I get a solver error (about a missing executable) when I execute a standard problem with glpk:

WARNING: "[base]/Pyomo-4.2.10784-py3.5.egg/pyomo/solvers/plugins/solvers/GLPK_old.py", 68, executable
Could not locate the 'glpsol' executable, which is required for solver 'glpk'
Traceback (most recent call last):

...

ApplicationError: No executable found for solver 'glpk'

Using

conda list

yields

derapproximator           0.52                    py35_10    cachemeorg
...
funcdesigner              0.5620                  py35_10    cachemeorg
...
glpk                      4.57                         10    cachemeorg
...
ipopt_bin                 3.7.1                        10    cachemeorg
... 
openopt                   0.5625                  py35_10    cachemeorg
...
pyomo                     4.2.10784               py35_10    cachemeorg
pyomo.extras              2.0                     py35_10    cachemeorg
...
pyro4                     4.41                    py35_10    cachemeorg
... 
pyutilib                  5.2.3601                py35_10    cachemeorg
...
serpent                   1.12                    py35_10    cachemeorg
setproctitle              1.1.9                   py35_10    cachemeorg
...
suds-jurko                0.6                     py35_10    cachemeorg
...

So the glpk package seems to be there.

Is this a bug or am I missing something?

Thanks in advance!
