hello！ My system is Ubuntu 20.04 with ROS 1. When I run “conda env create -f environment.yml” according to the README, the following error occurs: Pip subprocess error: ERROR: Ignored the following versions that require a different python version: 1.2.0 Requires-Python >=3.9; 1.2.1 Requires-Python >=3.9; 1.2.1rc1 Requires-Python >=3.9; 1.3.0 Requires-Python >=3.9; 2.10.1 Requires-Python <3; 2.11.0 Requires-Python <3; 2.11.1 Requires-Python <3; 2.4.0 Requires-Python <3; 2.4.1 Requires-Python <3; 2.4.2 Requires-Python <3; 2.4.3 Requires-Python <3; 2.4.4 Requires-Python <3; 2.5.0 Requires-Python <3; 2.5.1 Requires-Python <3; 2.5.2 Requires-Python <3; 2.6.0 Requires-Python <3; 2.6.1 Requires-Python <3; 2.6.2 Requires-Python <3; 2.7.0 Requires-Python <3; 2.7.2 Requires-Python <3; 2.8.0 Requires-Python <3; 2.8.1 Requires-Python <3; 2.8.2 Requires-Python <3; 2.8.3 Requires-Python <3; 2.8.4 Requires-Python <3; 2.8.5 Requires-Python <3; 2.8.6 Requires-Python <3; 2.8.7 Requires-Python <3; 2.9.2 Requires-Python <3; 4.6.0 Requires-Python >=3.9

CondaEnvException: Pip failed.

How can I resolve this? I would greatly appreciate any help you can provide!

Additionally, the spawn_marker_centroids.py file mentioned in the README does not exist in the scr directory. Does this refer to either the spawn_clusters_points.py or spawn_objects.py file?
