How to plot a density from a .mrc file?

I want to plot a 3d array stored in a mrc file. But after open it, nothing is plotted. I also tried to add contour to it, but still failed. I think this function should be pretty basic. I must miss some critical steps.

You .mrc file seems to be ill-formatted.

Here is a correctly formatted one.

I used the python package mrcfile to convert a numpy array to a mrc file. And chimeara can plot it correctly. Maybe there is some inconsistency among those libraries or software and paraview.

Definitely possible, but hard to pinpoint.
