边做边学。有这个问题。

featurizer = DeepImageFeaturizer(inputCol="image",outputCol="features",modelName="InceptionV3")

lr = LogisticRegression(maxIter=1,regParam=0.03,elasticNetParam=0.5, labelCol="label")

sparkdn = Pipeline(stages=[featurizer,lr])
spark_model = sparkdn.fit(train)

出现错误

尝试为conda安装jdk-8重新安装py4j
