What steps will reproduce the problem?

A very simplified example:

class my_array(np.ndarray):
    # Define the fields of the structured array
    dtype = 'f8'

x = my_array((2,3))

This will crash.

Traceback

Hey @battaglia01, thanks for reporting. This is fixed in our latest version (5.4.2), so please update. I don't know if you're using Conda-forge packages, but that's the only way to get 5.4.2 at the moment.

However, after tried to open the array you created in the Variable Explorer, I got the following error:

Traceback (most recent call last):
  File "/home/carlos/Projects/spyder/spyder/spyder/plugins/variableexplorer/widgets/collectionsdelegate.py", line 182, in createEditor
    if not editor.setup_and_check(value, title=key, readonly=readonly):
  File "/home/carlos/Projects/spyder/spyder/spyder/plugins/variableexplorer/widgets/arrayeditor.py", line 662, in setup_and_check
    is_record_array = data.dtype.names is not None
AttributeError: 'str' object has no attribute 'names'

which is similar to the one you reported. So, we'll fix it in our next version (5.4.3), to be released in March.
