TypeError: 'AxesSubplot' object has no attribute '__getitem__'

[MarcoCast79]

Hi,

I fitted a spectrum and wanted to create the marginal plot with pyp_beagle 0.5.6 with a simple call:

pyp_beagle -r /home/marco/BEAGLE/BEAGLE-general/results/fit_allparam_speconly/ --plot-marginal

but I get the following error:

Traceback (most recent call last): File "/home/marco/anaconda2/bin/pyp_beagle", line 11, in sys.exit(main()) File "/home/marco/anaconda2/lib/python2.7/site-packages/pyp_beagle/command_line.py", line 228, in main my_spectrum.plot_marginal(ID, file_names[i]) File "/home/marco/anaconda2/lib/python2.7/site-packages/pyp_beagle/beagle_spectra.py", line 400, in plotmarginal axs = axs[0,:] TypeError: 'AxesSubplot' object has no attribute 'getitem'

With pyp_beagle 0.4 I had no problems and the marginal plot was created (but there was no autoscale of the spectrum plot)

I have no problems with the triangle plot.

Do I have to upgrade something? Is there something wrong with my configuration? Thanks!

Which version of matplotlib are you using?

[MarcoCast79]

I'm using matplotlib 2.0.0

@MarcoCast79 the fix in https://github.com/jacopo-chevallard/PyP-BEAGLE/issues/29 didn't solve this issue for you?

[MarcoCast79]

actually not, I'm getting a different error though

likely I'm doing some mistake myself, here is the command following Alba's comment:

pyp_beagle -r /node4/data1/beagle/BEAGLE-general/results/fit_VANDELS_CDFS006520_allparam_speconly/ -p fit_VANDELS_CDFS006520_allparam_speconly.param --verbose -d --plot-marginal --wl-units ang --wl-range 3845 3915 4075 4125 4325 4385 4845 4880 4940 5030 5860 5895 6525 6620 6700 6750 --wl-rest --log-flux --show-residual --plot-line-labels --draw-steps

and here is the error:

I think you must have some negative fluxes somewhere, and so when you try to plot in log scale you get Inf

Try to rerun the command without the —log-flux option

[jacopo-chevallard]

The script doesn't run with a single range of wl (you still get the TypeError: 'AxesSubplot' object has no attribute 'getitem'), you should modify the code to solve this bug!
