How to fix SimpleQueue error when importing the Laspy module in Python?
Question:
When importing Laspy I get the following error:
import laspy as lp
ImportError: cannot import name ‘SimpleQueue’
The error occurs in the following line of the Laspy module:
from queue import Queue, SimpleQueue
I tried updating Python because it was likely to be a version issue, but this did not work. Then I tried updating Laspy, conda and lastly I updated everything. This did not work. I am using these versions:
python: 3.6.13
laspy: 2.3.0 (25/10/2022)
(I am working in Jupyter Notebook.)
How can I fix this error?
Answers:
SimpleQueue is new in Python 3.7.
You’ll need to use Python 3.7 or newer to use laspy – and you should, anyway, since Python 3.6’s end-of-life was 1 year and 3 months ago (23 Dec 2021).
Alternately, you can downgrade laspy to a version that does support Python 3.6; according to this commit versions older than 2.2.0 should be compatible.
