Can't use thermostate with any text editor, although it does run from console

DQuanR2 commented 5 years ago

I am not able to run any script outside the console (I have tried with Spyder and Sublime Text).

I followed the instructions for installing it. First I did it through pip where I tried to install only CoolProp.

And then I created a conda environment as suggested.

In both cases I only got CoolProp to work in the console but not in Spyder. I looked at the Python version used in the thermostate environment, copied the path and pasted it in spyder (tools -> preferences -> Python interpreter). However, I continue to get the same error message.

Code sample, preferably able to be copy-pasted and run with no changes

import CoolProp.CoolProp as CP fluid = 'Water' pressure_at_critical_point = CP.PropsSI(fluid,'pcrit') vL = 1/CP.PropsSI('D','P',1e5,'Q',0,fluid) vG = 1/CP.PropsSI('D','P',1e5,'Q',1,fluid)

Expected behavior

Thank you very much

It looks like you have a file named CoolProp/CoolProp.py. You can't do that, because then Python imports from that file instead of the library in the site-packages folder. Try renaming that folder and file, and see if it fixes the problem.

Thanks a lot for the quick response.

I changed the name but I still get a problem when importing CoolProp.

I get this error:

What if you run that file from the terminal, /path/to/anaconda/envs/thermostate/bin/python "/home/sofiapaz/Dropbox/TU Delft/Cursos/Cursos Q3/ME45160 Advanced Applied Thermodynamics/Simulacion/Test.py"? Can you be more specific about how you installed CoolProp, including the exact commands you used?

mdbernard commented 5 years ago

The "bad magic number" error results from having incompatible .pyc files in the module you're trying to import.

A potential fix is to go to the top level CoolProp directory and delete all the *.pyc files in it and all its subdirectories. This will let Python recreate .pyc files that are compatible with your current version of Python.

DQuanR2 commented 5 years ago

Thank for the responses. I tried deleting the .pyc files, but it didnt work. Then I deleted everything and did a fresh installation. Seems to be working now.

Thanks a lot!

Glad it works now!
