Dear UQWorld community,
I have been running the Bayesian Inference (BI) module of UQ[py]Lab to solve an inverse problem with PCE metamodels. The BI has already worked successfully for some synthetic test cases.
I am using AIES, with 120 walkers and 3000 iterations. This results in a quite long analysis.
My previous analysis was successfull with these hyper-parameters, despite a quite long analysis time (95h).
I am now trying to set the value of a few of my parameters to reduce the parameter space dimension. When re-running the BI with the same hyper-parameters, I encountered an error :
ConnectTimeout: HTTPSConnectionPool(host=‘uqcloud.ethz.ch’, port=443): Max retries exceeded with url: /update/2968517 (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x000002945A005F50>, ‘Connection to uqcloud.ethz.ch timed out. (connect timeout=None)’))
This error happened after a bit more than a 100 hours of analysis.
Note that the Session TimeOut is not a problem here, I set it up to a very high value in order not to encounter the Session TimeOut error.
Could you help me understanding what could be the cause of this ConnectTimeOut error ?
Could it be an internal time out parameter that overrides the user defined session time out ?
An other quick question: is there a way to access the results of previous analysis, or are they automatically destroyed ?
Thank you very much in advance for your insights on these questions.
