我正在尝试将元素列表作为 PipelineParameter 发送到轻量级组件。
这是重现该问题的示例。这是功能:
def my_func(my_list: list) -> bool:
print(f'my_list is {my_list}')
print(f'my_list is of type {type(my_list)}')
print(f'elem 0 is {my_list[0]}')
print(f'elem 1 is {my_list[1]}')
return True
如果我用这个执行它:
test_data = ['abc', 'def']
my_func(test_data)
它的行为符合预期:
my_list is ['abc', 'def']
my_list is of type <class 'list'>
elem 0 is abc
elem 1 is def
但是如果我将它包装在一个操作中并设置一个管道:
import kfp
my_op = kfp.components.func_to_container_op(my_func)
@kfp.dsl.pipeline()
def my_pipeline(my_list: kfp.dsl.PipelineParam = kfp.dsl.PipelineParam('my_list', param_type=kfp.dsl.types.List())):
my_op(my_list)
kfp.compiler.Compiler().compile(my_pipeline, 'my_pipeline.zip')
然后运行管道:
client = kfp.Client()
experiment = client.create_experiment('Default')
client.run_pipeline(experiment.id, 'my job', 'my_pipeline.zip', params={'my_list': test_data})
然后似乎在某些时候我的列表被转换为字符串!
my_list is ['abc', 'def']
my_list is of type <class 'str'>
elem 0 is [
elem 1 is '
