Attribute problem collections has no attribute callable

[hwillems2]

When I try to set up PHOEBE, I always get the same error as shown below. The Python script itself seems not to cause the problem:

`import matplotlib.pyplot as plt import phoebe

plt.rc('font', family='serif', size=14, serif='STIXGeneral') plt.rc('mathtext', fontset='stix') import phoebe import numpy as np

logger = phoebe.logger('error')

we'll set the random seed so that the noise model is reproducible

np.random.seed(123456789)

b = phoebe.default_binary() b.set_value('ecc', 0.2) b.set_value('per0', 25) b.set_value('teff@primary', 7000) b.set_value('teff@secondary', 6000) b.set_value('sma@binary', 7) b.set_value('incl@binary', 80) b.set_value('q', 0.3) b.set_value('t0_supconj', 0.1) b.set_value('requiv@primary', 2.0) b.set_value('vgamma', 80)

lctimes = phoebe.linspace(0, 10, 1005) rvtimes = phoebe.linspace(0, 10, 105) b.add_dataset('lc', compute_times=lctimes) b.add_dataset('rv', compute_times=rvtimes)

b.add_compute('ellc', compute='fastcompute') b.set_value_all('ld_mode', 'lookup') b.run_compute(compute='fastcompute')

fluxes = b.get_value('fluxes@model') + np.random.normal(size=lctimes.shape) 0.01 fsigmas = np.ones_like(lctimes) 0.02

rvsA = b.get_value('rvs@primary@model') + np.random.normal(size=rvtimes.shape) 10 rvsB = b.get_value('rvs@secondary@model') + np.random.normal(size=rvtimes.shape) 10 rvsigmas = np.ones_like(rvtimes) * 20 b.set_value('latex_repr', component='binary', value='orb') b.set_value('latex_repr', component='primary', value='1') b.set_value('latex_repr', component='secondary', value='2')

b.add_dataset('lc', compute_phases=phoebe.linspace(0,1,201), times=lctimes, fluxes=fluxes, sigmas=fsigmas, dataset='lc01')

b.add_dataset('rv', compute_phases=phoebe.linspace(0,1,201), times=rvtimes, rvs={'primary': rvsA, 'secondary': rvsB}, sigmas=rvsigmas, dataset='rv01')

b.set_value_all('ld_mode', 'lookup')

afig, mplfig = b.plot(x='phases', show=True)`

This is the console log I got before I encountered the problem.

Do you know how to solve this problem?

Can you try upgrading readline and then rerunning? pip install -U readline

Hi,

this solved my problem, thank you very much.
