How to apply other parameter file?

[dlalstjq]

Hello! I'm a student studying cosmology
I installed montepython following README file and it worked when input file is input/example.param.
But I get error like under when input is another parameter file.
I don't know how to solve this problem, How can I solve this error?

(base) minsub@Lee:/home/minsub/data/montepython_public-3.6$ python montepython/MontePython.py run -p input/base2015TTTEEE.param -o chains/base2015TTTEEE -N 100000
/!\ PyMultiNest detected but MultiNest likely not installed correctly. You can
safely ignore this if not running with option -m NS

Hi,

For each new run (e.g. with a new parameter file) you need to create a new chains directory, you cannot run in an existing one.

This is all explained in the MontePython guides on the course page of Julien Lesgourgues and a recorded lecture from the CosmoTools18 school . You might also find useful information in the official MontePython paper . I hope this helps.

Best,

Thanks to advice.

I run the code with new directory, and I find the reason of error. I think something wrong in install planck likelihood part.

so I reset my computer and reinstall montepython, planck likelihood, but I faced new problems.

when I run before reset, "Testing pyembed configuration" returned yes. how do I solved this problem?

Thanks to answer.

Hi,

It looks like it's having problems with your Python installation. This can be tricky, you'll want to make sure it knows about the relevant python directories, that they're specified in the relevant system paths, and is trying to run the right python installation, although sometimes I've been able to install Planck with the python wrapper even when it throws some Python errors, it can be a bit finnicky. Also, you see it has a problem with your lapack installation and gives you a suggestion for what to do.

Since this is not a MontePython issue our help will be limited. Here are ways to get further information on installing Planck:

• The MontePython README: https://github.com/brinckmann/montepython_public#the-planck-likelihood-part
• The Planck README found in your Planck directory at code/plc_3.0/plc-3.01/readme.md
• Searching for Planck in open and closed MontePython issues as common problems have been addressed many times: https://github.com/brinckmann/montepython_public/issues?q=is%3Aissue+Planck
• Searching for answered Planck issues on the CosmoCoffee forums https://cosmocoffee.info/
