Both CLASS and Hi_class installing error
Dear All,
I have the same installing problem with both CLASS and Hi_Class. Please, refer to the attached image for an error message that I got. Previously, I had no problem with the installation of both codes, but this time I do not know what I have been doing wrong. Could anyone help or provide me with a solution to the error.
Thank you in advance.
P.S: I have been trying to install on macOS Catalina (10.15.5), where gcc-4.9 is also installed.
Best,
Gansukh. T

Re: Both CLASS and Hi_class installing error
Do you have cython installed? If you do
in your terminal, does it give you an error or does it succeed?
Code: Select all
python -c "import cython"

Re: Both CLASS and Hi_class installing error
First of all, thank you for your comment.
Yes, I have "Cython version 0.29.20" installed as you can see in the attached image, and "python -c "import cython" seems to be okay since it does not compile to an error.
Do you think there is some incompatibility kind of issue with upgraded macOS?

Re: Both CLASS and Hi_class installing error
The error seems to come from
right?
Does that command work for your python? If not, you could try updating your cython / using anaconda python.
If you don't need the python wrapper, you can check that CLASS itself works, without the python wrapper - instead of 'make', run 'make class'.
Code: Select all
from Cython.Distutils import build_ext

Re: Both CLASS and Hi_class installing error
Dear Tanvi Karwal,
Thank you for your kind help.
At first,
compiled into an error hence I took your advice and have updated the Cython using anaconda. Now it seems there is no python related error because
command gives the following lines at the end:
However, when I try "import classy" from python, I got the following error message
and do you have any idea what could possibly be causing it?
Thank you in advance.

Re: Both CLASS and Hi_class installing error
I'm not sure, but more quick things to check:
- Check if this file actually exists
- Check if you're calling classy from the same python that you used to build it - i.e.
should return the anaconda3 installation.
I'm also surprised you got class to install using clang? Maybe it's because I tried on a much older Mac, but clang wouldn't cooperate with openmpi for me and I had to get gcc. But that's neither here nor there. Have you looked through the issues on GitHub for any matches of your problem?

Re: Both CLASS and Hi_class installing error
Thank you for your prompt reply. I have just checked the suggestions you made.
Yes, there exists
and it seems I am calling classy from while "which python" returns to
I think it is worth mentioning that I had installed python 3.7 prior to installing anaconda (which I just did yesterday). So, I suspect there might be a path defining issue when it calls python (and its libraries). Here, I am not sure whether I am calling classy is from previously installed python 3.7 or from anaconda3.
If that matters, I am using the MacBook (Late 2013). It is the same here that the clang does not cooperate with OPENMPI hence I also use GCC and GCC version that I am using is:
For me, GCC seems to be fine because there is no issue with "make class".
Lastly, I followed Github issues and, as you may know, there were no issues related to classy mentioned. To me, it seems there is an issue with my python and I am not being able to figure that out...

Re: Both CLASS and Hi_class installing error
I think the problem is solved. I was messed up with python versions. Finally, I set up my python as anaconda and updated my gcc to gcc-7 and it worked.
Thank you for your kind help!
