Created np.dtype, assigned np.dtype to array. Attempted to open array from variable explorer and got "Spyder has encountered an internal problem.

I think it's not possible for Spyder to show an array in this case. So need to show a message about it.

Is this problem resolved? I am also facing the same issue. When I try to open an array the spyder shows the error that it has some internal issue. Could you please guide how to resolve it?

[Hyypeer]

Same problem here ... everything is up to date.. Is someone working on this problem ???

[bcolsen]

Giving a some code to reproduce the error would help.

[lalita90]

My code runs fine but when I try to open array such as img_norm variable in this case, it shows this error and I can't see the values without printing the whole array.

@lalita90 What does it say in show details?

@lalita90 You don't have this bug. You have #8582, which is fixed in 3.3.3. To fix it please upgrade to the latest version of Spyder by opening the Anaconda Prompt and typing:

conda update spyder

[lalita90]

Thanks for referring me to #8582. I already updated everything but nothing worked out. Just had to downgrade my numpy version to 1.15.0. It may be useful for someone else in the future.
