Is HQ-SAM still available?

[chameroy]

When I try importing HQ-SAM:
from samgeo.hq_sam import SamGeo

I receive the following error message:
NameError: name 'SamPredictor' is not defined

Is HQ-SAM no longer available, or is this a bug I should report?

I'm facing the same issue. I'm waiting for a response.

HQ-SAM is still supported in the current segment-geospatial release, but it is an optional dependency. Installing only the base package can produce this exact error.

In the current source, samgeo/hq_sam.py imports SamPredictor from segment_anything_hq. If that import fails, the module prints an installation message, but it later defines SamGeoPredictor(SamPredictor), which is why the visible exception becomes:

NameError: name "SamPredictor" is not defined

Install the HQ extra with the same Python interpreter used by the notebook:

python -m pip install -U "segment-geospatial[hq]"

Then restart the Jupyter kernel/runtime and verify both imports:

python -c "from segment_anything_hq import SamPredictor; from samgeo.hq_sam import SamGeo; print(\"HQ-SAM import OK\")"

In a notebook, this is safer than a bare pip command because it targets the active kernel environment:

import sys
!{sys.executable} -m pip install -U "segment-geospatial[hq]"

Restart the kernel after that cell, then:

from samgeo.hq_sam import SamGeo

sam = SamGeo(model_type="vit_h", automatic=True)

If it still fails, these diagnostics will show whether Jupyter is using a different environment or a local file is shadowing the package:

import sys
import segment_anything_hq

print(sys.executable)
print(segment_anything_hq.__file__)

The current project metadata explicitly defines the hq extra with segment_anything_hq, sam2, and timm:
https://github.com/opengeos/segment-geospatial/blob/main/pyproject.toml

So this is primarily a missing optional-extra issue, not removal of HQ-SAM. The import handler could also be improved to raise the original ImportError immediately instead of allowing the later, less-informative NameError.
