run the sql from tutorial/iris-dnn
%%sqlflow SELECT * FROM iris.train TO TRAIN DNNClassifier WITH model.n_classes = 3, model.hidden_units = [10, 10], train.epoch = 10 COLUMN sepal_length, sepal_width, petal_length, petal_width LABEL class INTO sqlflow_models.my_dnn_model;

oh , I found here is a same issue: ModuleNotFoundError #3124 I've pull the newest image (nowtime 2021.05.17 14:56:07) but it doesn't work.

But there is a clue for me and you pull request he remove a line in Dockerfile: pk del --purge py3-pip && \

so , I enter into my k8s_server_sqlflow-server docker container docker exec -itu root [your container id] /bin/bash

then,execute this to install pip3 to fix lackness of model six apk add py3-pip

finally it works well.
