Run the instance using rasa run and call the training method of rasa through the HTTP API. From the logs, it can be seen that the model has been trained and stored in the/tmp/tmp \* \* directory, but through callback\_ URL retrieval fails. Query the/tmp directory and find that the directory where the Generative model was just generated does not exist. Will rasa automatically delete temporary model files and their directories? The log is as follows: * * * 2023-07-31 09:26:04,976 [DEBUG] Start to created model package for path ‘/tmp/tmpo\_10b8sb/nlu-20230731-091555-furious-caulk.tar.gz’. 2023-07-31 09:26:18,808 [DEBUG] Model package created in path ‘/tmp/tmpo\_10b8sb/nlu-20230731-091555-furious-caulk.tar.gz’. 2023-07-31 09:26:19,077 [DEBUG] Starting new HTTPS connection (1): [api.segment.io:443](http://api.segment.io:443) 2023-07-31 09:26:19,778 [DEBUG] [https://api.segment.io:443](https://api.segment.io:443) “POST /v1/track HTTP/1.1” 200 21 2023-07-31 09:26:19,810 [DEBUG] Starting new HTTPS connection (1): [api.segment.io:443](http://api.segment.io:443) 2023-07-31 09:26:20,446 [DEBUG] [https://api.segment.io:443](https://api.segment.io:443) “POST /v1/track HTTP/1.1” 200 21 2023-07-31 09:26:20,732 [DEBUG] Asynchronous processing of request was successful.

Issue temporarily resolved I used the /model/train interface to train the model, and sent the trained model to another business server through callback\_url. The postback model always times out due to bandwidth issues between the two devices. The reason is that the default timeout period of aiohttp is 5 minutes, and rasa does not expose this timeout parameter. So my solution is to modify line 579 of rasa/server.py, `async with aiohttp.ClientSession() as session:` changed to `async with aiohttp.ClientSession(timeout=aiohttp.ClientTimeout(total=3000)) as session:` Temporarily set the timeout to 50 minutes, the problem is now resolved. It is hoped that the --request-timeout parameter setting of the rasa run command line can affect the timeout value of this callback.
