You are correct I just have tested it on my mac and no problems there though I use the exact same libraries? boost 1.75 and pulsar client 2.8 ( 84cfb3affa1ce5bc1db29baab5498205049019dd ). I also tried the backtrace with your suggestion , thanks for that.  First output with cv2 import first. Hangs again at second imread Second output with pulsar import first. Error at creating producer. I have now tested it on 3 different ubuntu machines (19.10, 20.04. and 20.10) and with boost 1.75 built from source or 1.71 with apt package manager and opencv-python or opencv-python-headless ( version 4.4.0.40 till 4.5.1.48 ) and not a single combination works. I have also simplified the code that just cv2,pulsar and json have to be imported. ` #!/usr/bin/env python3 import cv2 import pulsar import json def main(): client = {} client["audience"] = "pulsar_service" client["issuer_url"] = "https://example.com/auth/realms/test_company"; client["client_id"] = "pulsar-coco.detection.images" client["client_secret"] = "secret" client["grant_type"] = "client_credentials" temp_client = pulsar.Client( "pulsar+ssl://127.0.0.1:6651", use_tls=True, tls_trust_certs_file_path="./pulsar-test/ca.crt", authentication=pulsar.AuthenticationOauth2(json.dumps(client)), ) test_topic = "persistent://ml/test_company/test" print(f"Testing client {client} in Realm on topic {test_topic}") test_producer = temp_client.create_producer( topic=test_topic, send_timeout_millis=5000 ) img_list = [ "./pulsar-test/images/8375743808_a43f504e44_b.jpg", "./pulsar-test/images/8886531759_033e06ea68_b.jpg", ] for x in range(len(img_list)): print(f"{x} - Image") rnd_img = cv2.imread(img_list[x]) print("after imread") _, image_np_array = cv2.imencode(".jpg", rnd_img) print("after imencode") image_byte_array = image_np_array.tobytes() print("after tobytes") # img_h, img_w, channels = rnd_img.shape # send to pulsar producer here... if __name__ == "__main__": main() ` Any advice on further debugging would be highly appreciated! thanks ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
