Plotting Broken

Plotting is broken with a dimension mismatch error. Here is a minimum working example:

import GPy
import numpy as np

x = np.linspace(0.0, 1.0, 100)[:, np.newaxis]
y = np.linspace(0.0, 1.0, 100)[:, np.newaxis]

model = GPy.models.GPRegression(x, y)

fig = model.plot()

This issue was mentioned in #723. The user mentions that f2py is having some issue, but does not specify a solution, so I’m reopening the issue here.

Ubuntu 18.04 (venv): python 3.6.7, GPy 1.9.6, scipy 1.2.1 and numpy 1.16.2 - plot doesn’t work As reported above

python -m pip install --upgrade --force-reinstall numpy==1.15.4 GPy scipy

Makes the plot work, however plotly output is giving deprecation watnings

plotly.graph_objs.Font is deprecated. Please replace it with one of the following more specific types

• plotly.graph_objs.layout.Font
• plotly.graph_objs.layout.hoverlabel.Font
• etc. plotly.graph_objs.Marker is deprecated.

Please replace it with one of the following more specific types

• plotly.graph_objs.scatter.Marker
• plotly.graph_objs.histogram.selected.Marker
• etc.

plotly.graph_objs.Line is deprecated. Please replace it with one of the following more specific types

• plotly.graph_objs.scatter.Line
• plotly.graph_objs.layout.shape.Line
• etc.

This error could be related to the latest release of numpy (v 1.16.0 on Jan 14th: https://pypi.org/project/numpy/1.16.0/#history).

On Mac OS X, the given model.plot example fails when updating the numpy version while keeping other dependencies constant. Works: GPy - 1.9.6 and numpy - 1.15.4 Doesn’t work: GPy - 1.9.6 and numpy - 1.16.0
