<p>在Booboo的帮助下,我能够更新代码以包含ProcessPoolExecutor。这是我的更新代码。总的来说,处理速度提高了60%以上</p>
<p>我确实遇到了一个处理问题,发现这个主题<a href="https://stackoverflow.com/questions/43836876/processpoolexecutor-works-on-ubuntu-but-fails-with-brokenprocesspool-when-r">BrokenPoolProcess</a>解决了这个问题</p>
<pre><code>output = {}
thePool = {}
def main(labelled_data, dictionaryRevised):
args = sys.argv[1:]
with ProcessPoolExecutor(max_workers=None) as executor:
for i in range(len(labelled_data)):
text = labelled_data['QueryText'][i]
arg = 'most_similar'+ ' '+ text
output = winprocess.submit(
executor, calculateScore, arg
)
thePool[output] = i #original index for future to request
for output in as_completed(thePool): # results as they become available not necessarily the order of submission
i = thePool[output] # the original index
text = labelled_data['QueryText'][i]
result = output.result() # the result
maximumKey = max(result.items(), key=operator.itemgetter(1))[0]
maximumValue = result.get(maximumKey)
labelled_data['SimilarText'][i] = maximumKey
labelled_data['SimilarityScore'][i] = maximumValue
return labelled_data, dictionaryRevised
if __name__ == "__main__":
start = time.perf_counter()
print("Starting to evaluate Query Text for labelling...")
output_Labelled_Data, output_dictionary_revised = preProcessor()
output,dictionary = main(output_Labelled_Data, output_dictionary_revised)
finish = time.perf_counter()
print(f'Finished in {round(finish-start, 2)} second(s)')
