Geometric data from postgis to neo4j

Hello everyone,

I'm new to NEO4j and would like to use it as a database to store navigation graphs between panoramic images (geotagged and dated images). I have the equivalent of this solution in a postgis database, and I would like to do it with neo4j as well.
I used the ETL integrated to neo4j to transfer my postgis data to my neo4j database, and I have some problems with the geometric data: How do I convert my geometric data from postgis to points on neo4j?

I saw that there is a NEO4j Spatial library, but the installation requires to be in a java environment, but I work in python.

How can I solve my problem? How can I get geometric data with Neo4j?

I thank you in advance and wish you a great day.
