Je suis relativement nouveau sur Python et j'essaie d'implémenter un module de multiprocessing pour ma boucle for.
J'ai un tableau d'URL d'images stockées dans img_urls dont j'ai besoin pour télécharger et appliquer une vision de Google.
if __name__ == '__main__':
img_urls = [ALL_MY_Image_URLS]
runAll(img_urls)
print("--- %s seconds ---" % (time.time() - start_time))
Ceci est ma méthode runAll ()
def runAll(img_urls):
num_cores = multiprocessing.cpu_count()
print("Image URLS {}",len(img_urls))
if len(img_urls) > 2:
numberOfImages = 0
else:
numberOfImages = 1
start_timeProcess = time.time()
pool = multiprocessing.Pool()
pool.map(annotate,img_urls)
end_timeProcess = time.time()
print('\n Time to complete ', end_timeProcess-start_timeProcess)
print(full_matching_pages)
def annotate(img_path):
file = requests.get(img_path).content
print("file is",file)
"""Returns web annotations given the path to an image."""
print('Process Working under ',os.getpid())
image = types.Image(content=file)
web_detection = vision_client.web_detection(image=image).web_detection
report(web_detection)
Je reçois ceci comme avertissement lorsque je l'exécute et que python plante
