API client attach data to task ssl error

[valavanisleonidas]

Hello team,

I am trying to attach data to a task using python cvat-sdk. I have 125 images of size 700MB and I get error

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='app.cvat.ai', port=443): Max retries exceeded with url: /api/tasks/1301577/data/ (Caused by SSLError(SSLError(5, '[SYS] unknown error (_ssl.c:2417)'))) 

python version  3.12.7
cvat_sdk        2.32.0

code

self.sdk_config = Configuration(
            host=CVAT_HOST,
            api_key={"Authorization": f"Token {self.token}"}
        )

    def upload_images(self, task_id: int, image_dir: str) -> None:
        
        image_files = [
            os.path.join(image_dir, f)
            for f in sorted(os.listdir(image_dir))
            if os.path.splitext(f)[1].lower() in UPLOAD_EXTENSIONS
        ]

        if not image_files:
            raise ValueError(f"No valid images found in {image_dir}")

        zip_path = os.path.join(image_dir, "upload.zip")
        with zipfile.ZipFile(zip_path, "w", zipfile.ZIP_DEFLATED) as zipf:
            for img in image_files:
                zipf.write(img, arcname=os.path.basename(img))
        print("send data")
        with ApiClient(self.sdk_config) as client:
            with open(zip_path, "rb") as f:
                task_data = DataRequest(
                    image_quality=70,
                    client_files=[f],
                    compression="ZIP"
                )

                (result, _) = client.tasks_api.create_data(
                    task_id,
                    data_request=task_data,
                    _content_type="multipart/form-data",
                    _request_timeout=(300, 600)
                )

        os.remove(zip_path)

I tried to increase the _request_timeout param but didnt work. If i upload batches of 50 images it works but it creates different jobs and i want them all in one.

Thank you in advance

Hi, please try to use the high-level SDK instead, example.
