H2OResponseErrorH2OResponseError：服务器错误java.lang.IllegalArgumentException：

Question

嗨，我在使用H2O教程从NLP运行AmazonReviews教程时遇到此错误

http://docs.h2o.ai/h2o-tutorials/latest-stable/h2o-world-2017/nlp/index.html

当我试图跑：

# Train Word2Vec Model
from h2o.estimators.word2vec import H2OWord2vecEstimator

# This takes time to run - left commented out
#w2v_model = H2OWord2vecEstimator(vec_size = 100, model_id = "w2v.hex")
#w2v_model.train(training_frame=words)

# Pre-trained model available on s3: https://s3.amazonaws.com/tomk/h2o-world/megan/w2v.hex
w2v_model = h2o.load_model("https://s3.amazonaws.com/tomk/h2o-world/megan/w2v.hex")

我收到以下错误：

Answer 1

其实我觉得我弄明白了。如果您正在运行本教程，请不要尝试下载该文件。只需取消评论以下内容即可

由此 ：

# This takes time to run - left commented out
#w2v_model = H2OWord2vecEstimator(vec_size = 100, model_id = "w2v.hex")
#w2v_model.train(training_frame=words)

对此：

# This takes time to run - left commented out
w2v_model = H2OWord2vecEstimator(vec_size = 100, model_id = "w2v.hex")
w2v_model.train(training_frame=words)

希望这有助于某人:)
