[BUG]: Use visualize.py failed

[Gang1024]

Description of the bug

When I want to draw a 2d or 3d image by plot_2d or plot_3d in visualize.py, it will report an error.
Error Message : "ValueError: too many values to unpack (expected 2). "
It happens on the first line of both two functions: X_domain, Y_domain = func.bounds.
Here is my guess about cause of the error:
The variable "func.bounds" has dimension "dim_default", it will be given to variable "X_domain" and "Y_domain".

Steps To Reproduce

1.run visualize.plot_2d(cec2017.F12017())
2.ValueError: too many values to unpack (expected 2)
