I have tried for hours, and just can't crack it! Does anyone know what is wrong with this code? `import colour XYZ = np.array([0.95045, 1, 1.08905]) figure, axes = colour.plotting.plot_chromaticity_diagram_CIE1976UCS( axes.plot(u, v, "o-", markersize=10, color="black") colour.plotting.render( I get /colour/models/cie_luv.py:386: RuntimeWarning: divide by zero encountered in divide Thanks in advance for any help you might offer. : )

Hi,
Same issues on my hardware.
divide by zero encountered in divide
xy = tstack([9 * u / d, 4 * v / d])
RuntimeWarning: invalid value encountered in multiply
[x[m_XY
Interesting.

I'm unfortunately going to bed but this may be a dependency issue? I'm using the latest colour but maybe we ought to compare our versions of numpy? I did not get a chance to look at the code throwing the error either... - J |

The warnings are not an issue, they occur when the chromaticity diagram colours are being computed, I thought I removed those but apparently not so I did another pass. There are a lot of divisions in Colour and we decided to handle the obvious ones that might get to 0 in the denominator. They should have been tamed in develop. |
