When I try to do 7 kernels together.
import numpy
import perfplot
perfplot.show(
setup=numpy.random.rand,
kernels=[
lambda a: numpy.c_[a, a],
lambda a: numpy.stack([a, a]).T,
lambda a: numpy.vstack([a, a]).T,
lambda a: numpy.column_stack([a, a]),
lambda a: numpy.concatenate([a[:, None], a[:, None]], axis=1),
lambda a: numpy.c_[a, a],
lambda a: numpy.stack([a, a]).T
],
labels=['c_', 'stack', 'vstack', 'column_stack', 'concat', 'c_1', 'stack1'],
n_range=[2**k for k in range(5)],
xlabel='len(a)'
)
I get this error:
IndexError Traceback (most recent call last)

IndexError: list index out of range
If I use automatic_order = False
, the error would not happen, but the result plot only show 6 of them.

I cannot reproduce the problem, and looking at the code I cannot see what this should occur. Are you running an old version of perfplot?

Closing for lack of feedback. Feel free to reopen at any time.

Sorry for the late feedback. You are right, I can't reproduce this error locally, including local Jubyter notebook. The error only happens on the colab.research.google.com platform. I install the perfplot
using !pip install -U perfplot
. I'm sharing this notebook:
