How to save the summaries not to the default path

env:
O-System Ubuntu 20.04
Graphic card RTX3090
run the DeepSpeech.py in container, which is built by the image 20.11-tf1-py3 from nvidia/tensorflow.

command:
python3 -u DeepSpeech.py
–train_files /workspace/de/clips/train.csv
–test_files /workspace/de/clips/test.csv
–dev_files /workspace/de/clips/dev.csv
–export_dir /workspace/DeepSpeech/data/model

final logs:

I Models exported at /workspace/DeepSpeech/data/model
I Model metadata file saved to /workspace/DeepSpeech/data/model/sun_616_1.md. Before submitting the exported model for publishing make sure all information in the metadata file is correct, and complete the URL fields.

there is no error or warning in the logs. After the testing I only get the pb and md file but without summaries for tensorboard. And I touch the default path, there are only the oldest summaries which were exported after the first training 3 days ago. No latest summaries in the default path.

Did I use the flag wrong? How can I get the latest summaries?

Thx a lot.
