how to install and use coolprop on ubuntu linux

[hyhzju]

I am new to linux and has never used python.

I spend many hours on reading instructions provided by the coolprop webpage: http://coolprop.sourceforge.net/HowGetIt.html#how-to-get-it

However, I still have no idea how to use this coolprop. I have installed python 2.7.6, cython, GCC 4.8.2. I also downloaded a few source package and tried "easy_install CoolProp" etc.

and downloaded: CoolProp-4.2.5.zip http://iweb.dl.sourceforge.net/project/coolprop/CoolProp/4.2.5/Python/CoolProp-4.2.5.zip

But what should I do next?

Is there any GUI installed to my system? Can I use "./configure--->make--->make install..." things like that for other program source code?

Why I can not find some real basic and easy-understanding instructions/tutorials for compile, setup, and usage this great software? Step by step.

I believe such a document will be very helpful to anyone who just start to try.

Given that you use Ubuntu, you should install pip. I think sudo apt-get install python-pip does the trick. After that you can get CoolProp from pypi by running sudo pip install coolprop or pip install coolprop --prefix /home/user/where/you/want/it.

@jowr is correct. After installing pip, to install coolprop you just need a

pip install coolprop

at the command prompt.

Thanks so much for the prompt reply!! That's really fast. I followed "start" from your linked webpage. That makes more sense. I realized that a few python packages were not properly installed. Those are: numpy scipy matplotlib matplotlib.pyplot After installed those, I typed the import command: import CoolProp.CoolProp as CP No error message now. However, after I input all those example code. I got nothing. No results printed on the screen.

Then I tried the other commands in python environment, I got

Could you help me on that?

I fear that image attachment does not work with github messaging system.

It's normal that nothing ended printed on the screen because nothing was sent there. For exemple, the next code

import CoolProp.CoolProp as CP
fluid = 'Water'
pressure_at_critical_point = CP.PropsSI(fluid,'pcrit')
# Massic volume (in m^3/kg) is the inverse of density
# (or volumic mass in kg/m^3). Let's compute the massic volume of liquid
# at 1bar (1e5 Pa) of pressure
vL = 1/CP.PropsSI('D','P',1e5,'Q',0,fluid)
# Same for saturated vapor
vG = 1/CP.PropsSI('D','P',1e5,'Q',1,fluid)
print(vL,vG)

would print the two computed values on the screen because I asked it to via the print statement. Otherwise, values are computed for later use but not printed. If I copy/paste these instruction in the interactive python, I also have to explicitly "ask" for vL and vG variables in order to get the values printed

>>> import CoolProp.CoolProp as CP
>>> fluid = 'Water'
>>> pressure_at_critical_point = CP.PropsSI(fluid,'pcrit')
>>> # Massic volume (in m^3/kg) is the inverse of density
... # (or volumic mass in kg/m^3). Let's compute the massic volume of liquid
... # at 1bar (1e5 Pa) of pressure
... vL = 1/CP.PropsSI('D','P',1e5,'Q',0,fluid)
>>> # Same for saturated vapor
... vG = 1/CP.PropsSI('D','P',1e5,'Q',1,fluid)
>>> vL
0.0010431536977168858
>>> vG
1.6939276653850723

@jjfPCSI1 Thanks so much. It works. Cool. I am leaning a lot here and still learning it. I think I am getting more and more familiar with this great code, and 'm going to link it to my Fortran code as well as the Libreoffice Calc.

By the way, is there any GUI available for CoolProp? just like refprop?

[ibell]

Good to hear you got things working. No, I'm afraid we don't have a gui, it would be lots of work, want to write it? On Oct 24, 2014 10:57 AM, "hyhzju" notifications@github.com wrote:

I only have experience with VB 6.0 and VB.NET programming for GUI. Python is a completely new thing to me. Currently I am visiting ME school at Purdue University and the schedule is full.

I do wish to be able to call the CoolProp library in LibreOffice Calc at the first step and write an good interface for general calculation.

I noticed a conversation posted on the google group: https://groups.google.com/forum/#!topic/coolprop-users/1l4TxPGZBnI. It suggested to copy the attached coolprop.py to the directory $home/.config/libreoffice/4/. After google "libreoffice + python +macro", I learned that it should be more precisely to $home/.config/libreoffice/4/usr/Scripts/Python/. Or, put the file to /usr/lib/libreoffice/share/Scripts/python/, where I can find some other example python script macro, such as HelloWorld.py.

After loading the Libreoffice Calc I can find "coolprop" in menu Tools/Macros/Organize Macros/Pyhon/Libreoffice Macros/coolprop.

However, when I open the TestLibreOfficePy-3.ods file downloaded from the google group conversation, (Enable macro under security options), I got an error message,

---

BASIC runtime error. An exception occurred Type: com.sun.star.script.provider.ScriptFrameworkErrorException Message: <class 'pythonscript.com.sun.star.ucb.InteractiveAugmentedIOException'>: an error occurred during file opening /usr/lib/libreoffice/program/pythonscript.py:428 in function getModuleByUrl() [lastRead = self.sfa.getDateTimeModified( url )] /usr/lib/libreoffice/program/pythonscript.py:992 in function getScript() [mod = self.provCtx.getModuleByUrl( fileUri )]

.

The code line "oScript = oMSP.getScript(sURL)" was highlighted in the function invokePyFunc(). It seems the file name passed to that function was not correct/accepted.

What's wrong there? Can anyone help me?

Are you on windows? If so, LibreOffice is quite easy to interface with - its just like using Excel. See the docs at http://www.coolprop.dreamhosters.com:8010/sphinx/coolprop/wrappers/LibreOffice/index.html#libreoffice

Doh I just re-read your subject line again. Linux. Let's see if I can figure out what is going on.

Ok, I got it working. Here's a recipe:

Make a folder for the script to reside in

mkdir -p ~/.config/libreoffice/4/user/Scripts/python/

Copy the dowloaded .py file to the folder you made (adjust download path

as necessary) cp ~/Downloads/coolprop.py ~/.config/libreoffice/4/user/Scripts/python/

Install python script provider (uses python 3)

sudo apt-get install libreoffice-script-provider-python

pyton scripting in LibreOffice uses python3, make sure we populate the

right python site-packages folder sudo apt-get install python3-pip sudo pip3 install Cython

Compile CoolProp v5+ manually

you need to have numpy and matplotlib already - you can do sudo apt-get

install python3-matplotlib git clone http://github.com/CoolProp/CoolProp --recursive cd CoolProp/wrappers/Python sudo python3 setup.py install

Open example in LibreOffice

I think that error is because it wants it in the ~/.config/... location. See my recipe below

I followed your recipe and It works perfectly! Thanks. I want to mention that previously, 1) I created a fold "Python" instead of "python" in the ~/.config/libreoffice/4/user/Scripts directory 2) I was using Python 2.7.6 instead of 3.x

3. I was using CoolProp 4.2.6 I don't know if they matter. but anyway, the problem is solved now.

Excellent news. LO support for python is pretty rough and badly documented. Glad to hear it works now! On Oct 27, 2014 3:24 PM, "hyhzju" notifications@github.com wrote:
