Bug#1073547: pytorch-geometric: tests fail with scipy 1.13

[Drew Parsons]

Source: pytorch-geometric
Version: 2.4.0-2
Severity: important
Control: affects -1 src:scipy

pytorch-geometric is failing tests with scipy 1.13 from experimental,
evidently due to use of a deprecated API.

The error message is

scipy 1.12 has only recently been uploaded to debian, but upstream is
already preparing 1.14, so we can expect to upload 1.13 in the near
future.
