我已成功运行 ML Pipeline 实验，并顺利发布了 Azure ML Pipeline。当我在成功运行并发布后直接运行以下命令时（即我正在使用 Jupyter 运行所有单元格），测试失败！
interactive_auth = InteractiveLoginAuthentication()
auth_header = interactive_auth.get_authentication_header()
rest_endpoint = published_pipeline.endpoint
response = requests.post(rest_endpoint,
headers=auth_header,
json={"ExperimentName": "***redacted***",
"ParameterAssignments": {"process_count_per_node": 6}})
run_id = response.json()["Id"]
这是 azureml-logs/70_driver_log.txt 中的错误：

例外：找不到临时文件。作业失败。作业应生成临时文件或在此之前失败。请检查日志以查找原因。
以下是 logs/sys/warning.txt 中的错误：

具有相同的 URL。
下一个...
当我等待几分钟并重新运行以下代码/单元格时。
interactive_auth = InteractiveLoginAuthentication()
auth_header = interactive_auth.get_authentication_header()
rest_endpoint = published_pipeline.endpoint
response = requests.post(rest_endpoint,
headers=auth_header,
json={"ExperimentName": "***redacted***",
"ParameterAssignments": {"process_count_per_node": 2}})
run_id = response.json()["Id"]
顺利完成！？嗯？ （我在这里更改了进程计数，但我认为这没有什么区别）。此外，日志中没有用户错误。
关于这里可能发生什么的任何想法？
提前感谢您提供的任何见解，并祝您编码愉快！:)
========== 更新#1：==========
在 1 个文件上运行约 300k 行。有时这项工作有效，有时则无效。我们已经尝试了许多具有不同配置设置的版本，都会不时导致失败。将 sklearn 模型更改为使用 n_jobs=1。我们正在对 NLP 工作的文本数据进行评分。
default_ds = ws.get_default_datastore()
# output dataset
output_dir = OutputFileDatasetConfig(destination=(def_file_store, 'model/results')).register_on_complete(name='model_inferences')
# location of scoring script
experiment_folder = 'model_pipeline'
rit = 60*60*24
parallel_run_config = ParallelRunConfig(
source_directory=experiment_folder,
entry_script="score.py",
mini_batch_size="5",
error_threshold=10,
output_action="append_row",
environment=batch_env,
compute_target=compute_target,
node_count=5,
run_invocation_timeout=rit,
process_count_per_node=1
)
我们的下一个测试将是 - 将每一行数据放入自己的文件中。我只尝试了 30 行，即 30 个文件，每个文件有 1 条记录用于评分，但仍然得到相同的错误。这次我将错误阈值更改为 1。

在它完成的回合中，只返回一些记录。一次返回的记录数我认为是 25 或 23，另一次是 15。
========== 更新 #2：12/17/2020 ==========
我删除了我的一个模型（我的模型是 15 个模型的重量混合）。我什至清理了我的文本字段，删除了所有的制表符、换行符和逗号。现在我正在为 30 个文件评分，每个文件有 1 条记录，有时工作会完成，但它不会返回 30 条记录。其他时候它返回一个错误，并且仍然得到“没有找到临时文件”错误。
