Hi, I haven’t succeed in using SageMath plotting by the show function on Windows. After a fresh install at the root folder C:\sagemath\ (in lower-case and not in \home directory as it’s recommended in the help pages on sage google group), I can’t produce the last line of this short script (below), and an alert window always writes that something goes wrong ("It seems that the kernel has crashed"). As I don’t know Sagemath for a long time, could anyone help? I’m sure you’re keen on doing a perfect install on Windows just by downloading binaries and running the installer, for the sake of users as it is written on the original website about Windows installation. Thank you so much for taking the time to read my post.

Here the executed lines in Jupyter:

m = random_matrix(RDF,500)
e = m.eigenvalues()
w = [(i, abs(e[i]))for i in range(len(e))]
show(points(w))  # it seems that the kernel has crashed

At the end, I’ve installed the "SageMath-9.1-Installer-v0.6.0" of the date : 2020-07-29 15:45, on a fresh install of Windows 10, and now graphs are printed in notebooks and in sagemath console. The laters v0.6.1 and v0.6.2 have a kernel that doesn’t print graphs and as a consequence, provoke a kernel crash (on the same fresh install of Windows 10 64 bits).
