There aremanyways to save a Python dictionary to file, and then load it into memory later. The five techniques I use most often are: pickle, json, numpy, string serialization, and custom function. Each technique has pros and cons. Suppose you have a Python dictionary like so: src_dict =...
dictionary = corpora.Dictionary(texts) # word must appear >10 times, and no more than 40% documents dictionary.filter_extremes(no_below=40, no_above=0.1) # save dictionary dictionary.save('dict_v1.dict') # load corpus 加载语料库 corpus = [dictionary.doc2bow(text) for text in texts] #...

这种方法可以通过使用pickle模块将字典保存到磁盘上,并在需要时按需加载。 importpickle# 将字典保存到文件defsave_dict_to_file(dictionary,filename):withopen(filename,'wb')asfile:pickle.dump(dictionary,file)# 从文件加载字典defload_dict_from_file(filename):withopen(filename,'rb')asfile:returnpickle.l...
print('Extracted Features: %d'% len(features))# save to filedump(features, open('features.pkl','wb')) 运行该数据准备步骤可能需要一点时间,时间长度取决于你的硬件,带有 CPU 的现代工作站可能需要一个小时。 运行结束时,提取出的特征将存储在 features.pkl 文件中以备后用。该文件大概 127 Megabytes 大...

# TODO: Save the resulting PDF to a file. 对于每个 PDF,循环通过调用open()并使用'rb'作为第二个参数,以读取二进制模式打开一个文件名。open()调用返回一个File对象,该对象被传递给PyPDF2.PdfFileReader()为该PDF 文件创建一个PdfFileReader对象。 第三步:添加各页面 对于每一个 PDF 文件,除了第一页之外...
