IO Error when running runFixedPop

[james-s-willis]

When running:

(cosmic) [willis@scarlet willis]$ runFixedPop --final_kstar1 11 --final_kstar2 10 11 --inifile Params.ini --galaxy_component ThinDisk --metallicity 0.02 --convergence-params mass_1 mass_2 sep ecc --initial_samp multidim --Nstep 15000 --Niter 1000000000 -n 2

I get the following IO error:

I am following the documentation at: https://cosmic-popsynth.github.io/fixedpop/index.html#sample-command-line

I am running Ubuntu 18.04.2, Python 2.7.16, Anaconda 2019.03 and gfortran 7.4.0. @katiebreivik

Hey @james-s-willis I tried to reproduce your issue, and am having trouble doing so. I am wondering if you could list the versions of pandas and h5py you have in your conda environment as well? The

Opening dat_ThinDisk_11_10_11.h5 in read-only mode

is odd and I have never seen that before in the standard out.

Also, not that we should not be backwards compatible, but I will probably need to set up a py27 virtualenv to really try to reproduce the error so may take a second.

Thanks!

Hi Scotty,

Thanks for the quick response. I tried the same command again today and it seems to be working now. So I was going to close this issue.

I was using h5py 2.9.0 and pandas 0.24.2

Thanks again,

James
