ecflow_ui problem

[19950813]

I installed ecflow using the conda command on the mac system, but I am using ecflow _ui, the process will die, the pop-up interface also always shows loading, after forcibly closing, it will report an error prompt "Error, unable to parse JSON session file : /Users/lijinxiong/.ecflow_ui_v5/default.session/session.json: cannot open file Terminated: 15"

Hello @19950813 , I wonder if something corrupted your settings file? I suggest you do something like: mv /Users/lijinxiong/.ecflow_ui_v5 /Users/lijinxiong/.xxecflow_ui_v5 and try again. Best regards, Iain

Teacher, I just tested the method you provided, but the effect is not ideal. Below I will post a detailed startup log:

Hello @19950813 , I would need more details to resolve the problem:

• what command and what flags did you use to start up ecflow_ui?
• do you have any env variables defined starting with ECFLOWUI before starting up ecflow_ui?
• does the /Users/lijinxiong/.ecflowrc directory exist?
• does the /Users/lijinxiong/.ecflow_ui directory exist and contain a folder called "default.session"?

Best regards, Sandor

[19950813]

Hello @sandorkertesz , in response to your question, I will mainly answer the following points:

• I used conda install ecflow to download ecflow. After downloading, I directly started the software via ecflow_ui on the command line
• Before startup, no environment variables starting with ECFLOWUI are defined -The path /Users/lijinxiong/.ecflowrc exists on my mac
• /Users/lijinxiong/.ecflow_ui/ contains a folder named default.session

Trouble you

[sandorkertesz]

Hello @19950813 , Thank you for the quick reply. This is what I suggest:

• mv /Users/lijinxiong/.ecflow_ui_v5 /Users/lijinxiong/.ecflow_ui_v5.backup
• mv /Users/lijinxiong/.ecflow_ui /Users/lijinxiong/.ecflow_ui.backup
• start up ecflow_ui again

I hope it will work for you.

Hello @sandorkertesz , I performed the operation according to your prompt, but it still cannot be started. After entering ecflow_ui, a window pops up, but the window is in a stuck state. The following is the log after I forcibly closed the window:

Trouble you

[sandorkertesz]

Hello @19950813 , I am sorry to hear that. There is a slight chance that there is something to do with Qt (the ui framework we use for ecflow_ui) on MacOS. I suggest you try these steps now:

• rm -Rf /Users/lijinxiong/.ecflow_ui_v5
• export QT_MAC_WANTS_LAYER=1
• start ecflow_ui again with ecflow_ui -log (it will dump all the logs to the stdout)

I wonder if it changes anything. Many thanks, Sandor

[19950813]

Thank you very much. After operating according to your steps, it can be displayed normally. For the specific situation, you can see the following two screenshots:

Hello @19950813 , just before I close this issue, I will recommend that you install the latest version of ecFlow, 5.7.0. We made some improvements in the startup, as well as various other improvements. Best regards, Iain

[19950813]

Ok sir, thanks for your help @iainrussell
