+
+	You're running: MVTB==0.9.7, SMTB==1.1.13, NumPy==1.26.4, SciPy==1.14.1,
+                    Matplotlib==3.10.0, OpenCV==4.10.0, Open3D==0.18.0

+
+	matplotlib interactive mode on
+
+	func/object?       - show brief help
+	help(func/object)  - show detailed help
+	func/object??      - show source code

+	Type 'copyright', 'credits' or 'license' for more information
+	IPython 8.31.0 -- An enhanced Interactive Python. Type '?' for help.
+	Using matplotlib backend: macosx
+
+	>>> im = Image.Read("monalisa.png")
+
+	>>> im.disp()
+	Out[2]: <matplotlib.image.AxesImage at 0x1690e9720>
+
+It has the advantage of command history, tab completion, and inline help.
