log_image fails to log metadata when annotations=[]

[njacobs2019]

Describe the Bug

Experiment.log_image successfully logs an image but fails to log metadata. This happens when annotations are set to an empty list.

Expected behavior

I expected Comet to log the image and metadata or throw an error that the list is empty.

Where is the issue?

• Comet Python SDK
• Comet UI
• Third Party Integrations (Huggingface, TensorboardX, Pytorch Lighting etc)

To Reproduce

Run this script

import os

import comet_ml
import numpy as np
from dotenv import load_dotenv

load_dotenv()


experiment = comet_ml.start(
    api_key=os.getenv("COMET_API_KEY"),
    project_name="TEST_PROJECT",
    mode="create",
    online=True,
    experiment_config=comet_ml.ExperimentConfig(
        auto_metric_logging=False,
    ),
)


img = np.random.rand(10,10)
annotations = []
metadata = {"key": "example value"}

experiment.log_image(
    name="TEST_IMAGE",
    image_data=img,
    annotations=annotations,
    metadata=metadata,
)

Additional context

Comet successfully logs metadata when annotations is set to None.
