3. Double click on the first element and change it from 0 to 5

4. Click OK

5. Got this error report pop up

File "/Users/measejm1/anaconda/envs/python3_general/lib/python3.6/site-packages/spyder/widgets/variableexplorer/arrayeditor.py", line 384, in setEditorData
text = from_qvariant(index.model().data(index, Qt.DisplayRole), str)
File "/Users/measejm1/anaconda/envs/python3_general/lib/python3.6/site-packages/spyder/widgets/variableexplorer/arrayeditor.py", line 253, in data
value = self.get_value(index)
File "/Users/measejm1/anaconda/envs/python3_general/lib/python3.6/site-packages/spyder/widgets/variableexplorer/arrayeditor.py", line 247, in get_value
return self.changes.get((i, j), self._data[i, j])
IndexError: too many indices for array

What is the expected output? What do you see instead?
Expected the first element to be changed to 5 in the workspace

@andfoy, please take a look at this one. I think it only happens with 1D Numpy arrays.
