python-3.x - Python H2O 脚本：结束/关闭时的 TypeErrors

问题描述

文件h2otest.py包含https://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/glm.html上的代码的缩短版本：

import h2o
h2o.init()
from h2o.estimators.glm import H2OGeneralizedLinearEstimator
prostate = h2o.import_file("https://h2o-public-test-data.s3.amazonaws.com/smalldata/prostate/prostate.csv")
prostate['CAPSULE'] = prostate['CAPSULE'].asfactor()
prostate['RACE'] = prostate['RACE'].asfactor()
prostate['DCAPS'] = prostate['DCAPS'].asfactor()
prostate['DPROS'] = prostate['DPROS'].asfactor()
predictors = ["AGE", "RACE", "VOL", "GLEASON"]
response_col = "CAPSULE"
glm_model = H2OGeneralizedLinearEstimator(family="binomial", lambda_= 0, compute_p_values=True)
glm_model.train(predictors, response_col, training_frame= prostate)
print('Finished')

我在 Conda 环境pycharm中的命令行上运行代码，其中 h2o 3.30.1.3 是从 PyPi 安装的。我正在使用 Python 3.8。我在我的 Mac 和 Linux 服务器上都遇到了同样的错误。启动时没有现有的 H2O 服务器：

(pycharm) $> python h2otest.py

该代码完成了它的工作，但在最后给出了错误消息：

...

我怎样才能摆脱那些错误信息？
