1.首先,您需要從Google下載預訓練的模型,然後放入文件夾(egbert_base_dir)
chinese_L-12_H-768_A-12 from <a href='https://storage.googleapis.com/bert_models/2018_11_03/chinese_L-12_H-768_A-12.zip'>bert</a>
2.第二,您需要擁有培訓數據(例如Train.TSV)和驗證數據(例如Dev.TSV),然後將其放在
folder(e.g.TEXT_DIR ). you can also download data from here <a href='https://pan.baidu.com/s/1ZS4dAdOIAe3DaHiwCDrLKw'>data to train bert for AI challenger-Sentiment Analysis</a>.
it contains processed data you can run for both fine-tuning on sentiment analysis and pre-train with Bert.
it is generated by following this notebook step by step:
preprocess_char.ipynb
you can generate data by yourself as long as data format is compatible with
processor SentimentAnalysisFineGrainProcessor(alias as sentiment_analysis);
data format: label1,label2,label3t here is sentence or sentencest
it only contains two columns, the first one is target(one or multi-labels), the second one is input strings.
no need to tokenized.
sample:"0_1,1_-2,2_-2,3_-2,4_1,5_-2,6_-2,7_-2,8_1,9_1,10_-2,11_-2,12_-2,13_-2,14_-2,15_1,16_-2,17_-2,18_0,19_-2 浦东五莲路站,老饭店福瑞轩属于上海的本帮菜,交通方便,最近又重新装修,来拨草了,饭店活动满188元送50元钱,环境干净,简单。朋友提前一天来预订包房也没有订到,只有大堂,五点半到店基本上每个台子都客满了,都是附近居民,每道冷菜量都比以前小,味道还可以,热菜烤茄子,炒河虾仁,脆皮鸭,照牌鸡,小牛排,手撕腊味花菜等每道菜都很入味好吃,会员价划算,服务员人手太少,服务态度好,要能团购更好。可以用支付宝方便"

生成原始數據:[在這裡添加一些東西]
確保每行都是句子。在每個文檔之間都有一個空白行。
您可以從zip文件中找到生成的數據。
use write_pre_train_doc() from preprocess_char.ipynb
使用以下方式生成用於培訓階段的數據:
export BERT_BASE_DIR=./BERT_BASE_DIR/chinese_L-12_H-768_A-12
nohup python create_pretraining_data.py
--input_file=./PRE_TRAIN_DIR/bert_*_pretrain.txt
--output_file=./PRE_TRAIN_DIR/tf_examples.tfrecord
--vocab_file=$BERT_BASE_DIR/vocab.txt
--do_lower_case=True
--max_seq_length=512
--max_predictions_per_seq=60
--masked_lm_prob=0.15
--random_seed=12345
--dupe_factor=5 nohup_pre.out &
帶有生成數據的預訓練模型:
python run_pretraining.py
微調
python run_classifier.py
下載情感分析的緩存文件(令牌處於單詞級別)
訓練模型:
python train_cnn_fine_grain.py
cache file of TextCNN model was generate by following steps from preprocess_word.ipynb.
it contains everything you need to run TextCNN.
it include: processed train/validation/test set; vocabulary of word; a dict map label to index.
take train_valid_test_vocab_cache.pik and put it under folder of preprocess_word/
raw data are also included in this zip file.
帶有蒙版語言模型的預訓練文本
python train_cnn_lm.py
textcnn的微調
python train_cnn_fine_grain.py
with session and feed style you can easily deploy BERT.
