TypeError: unsupported operand type(s) for |: 'dict' and 'dict'

What happened?

Dear QUIMB organizers,

I tried to plot the last tensor network as shown in section: 2.8. ‘Publication style’ figures, but I get below error:

node_shape={tag: 'h' for tag in tags} | {tag0: 's'}, TypeError: unsupported operand type(s) for |: 'dict' and 'dict'

I am using the Python 3.8 via Anaconda 3. How can I resolve the problem?

I could plot other tensor networks.

What did you expect to happen?

I am using quimb version: 1.4.0

I could solve this problem by adding few lines as follows:

d1 = {tag: 'h' for tag in tags} d2 = {tag0: 's'} d = d1.copy() d.update(d2) ..... node_shape=d, ....

The union operator for dicts was added in python 3.9 I believe. While supporting python 3.8 in the actual code-base is still desirable, my feeling is this doc is fine as-is going forward.
