Remove lines from contour plot

📊 Plotly Python
1

I have this matrix for which I want to create a contour plot:

M = [[np.exp(-(i-j)**2/100) for i in range(100)] for j in range(100)]

I know how to create the contour plot:

fig = go.Figure()
fig.add_contour(z=M, contours_coloring='heatmap', contours_showlines=False)
fig.show()

newplot%20(5)
newplot (5).png700×450 81.8 KB

But, how can I remove the contour lines? contours_showlines=False does not appear to work.

I had the same problem in R plotly.

Try add
line = list(width = 0)
