CAMB on Mac

Post by CaixiaSkye Gao » April 10 2020

Dear All,

I installed Anaconda and tried to install camb:

conda install -c conda-forge camb

But failed. Attached please find the error code. Could you tell me how to solve this problem?

Thank you,
Caixia

I find anacomda often gets into an inconsistent state. I'd make a new clean environment, e.g. using

Code: Select all

conda create -n py37forge -c conda-forge python=3.7 scipy matplotlib camb

Thank you Dr. Lewis. That is very helpful. We did successfully installed the program.
When I run the example on Jupyter, It says there is no module camb found.

Make sure you are running the notebook in the right virtual env.

Yes, that is actually the case. CAMB was installed on a new environment py37forge, instead of the root. Then we tried to launch jupyter notebook in this environment, however, Jupyter notebook can not be installed in py37forge.
