DLL load failed while importing QtWebEngineWidgets #33

Thank you for posting a bug. I've ran a command:
C:/cae/bin/python/python.exe -m pip listand got
PyQt5 5.15.9 PyQt5-Qt5 5.15.2 PyQt5-sip 12.11.1 PyQtWebEngine 5.15.6 PyQtWebEngine-Qt5 5.15.2CAE startup script tests if all packages from
C:/cae/config/requirements_windows.txtwere installed. But there are no packagesPyQt5-Qt5,PyQt5-sipandPyQtWebEngine-Qt5in the requirements (sorry, its my fault). Please, check if you have them installed on your CAE's Python. If not, run:C:/cae/bin/python/python.exe -m pip install PyQt5-Qt5 PyQt5-sip PyQtWebEngine-Qt5Of cause, change path
C:/cae/bin/python/python.exeto yours one.Hi imirzov,
thanks for the feedback.
I am still working on it. There were conflicts between Python versions when trying to install PyQt...and the other requirements.
After digging into the web I learned something. I executed the following command inside windows powershell in the bin folder of the cae_20230122_v0.9.1_windows, "pip install --target=C:\Users\drppo\Documents\cae_20230122_v0.9.1_windows\bin\python PyQt5-Qt5 PyQt5-sip PyQtWebEngine-Qt5 PyQtWebEngine".
This was the only way I could see the Qt5 folders and files being created in that folder.When executing in powershell the command " -m pip install PyQt5-Qt5 PyQt5-sip PyQtWebEngine-Qt5 PyQtWebEngine" I was getting before, the following message: "Defaulting to user installation because normal site-packages is not writeable".
Some instances depending on the command I was trying I also got the "Requirement already satisfied" and this is, if I understood right, due to other Python versions installed on my Windows machine.
All that being said, now there are new problems, but related to a sip module.
Now when I run the command you gave, I get this as result, but the versions of the packages shown do no match those in the cae_...folder.
I can only guess that there might be a specifi command to check the version of these files in the folder I am, and not on the system, which is what I think is happening, hence the different versions.
Thank you again.
When you run command
pip listyou get list of packages installed on your OS's Python. I don't care about Python installed on your OS. You have to use Python embedded into CAE. That's why I used absolute paths to python.exe in my previous post. And don't usepip installwithtargetargument. Simply do what I've said in the previous post. Use Python from CAE/bin/python folder.I am trying again the comand you instructed and see once more below the output I get.
I got your point about local Python and not OS Python. I just mentioned that because I wanted to explain thoroughly what I have done, what I run into and where I was in the end. You could perhaps realize I did something wrong and give me a new feedback.
Not sure if my previous post was clear, but the first thing I did was to run the command you gave and that returned no PyQt installation/creation whatever in the python folder inside cae. That is the reason why I kept looking for information on the web.What am I doing wrong? I cant spot if there is something incorrect.
Well, if requirements are satisfied, then I have no idea why the app does not start. Sorry.
PyQtseems to be fickle. I have an idea to rewrite everything withtkinterbut have no free time at all.I might be doing something wrong, unbekownst to myself.
I will learn something about managing Python within a machine and across different versions and will try again repeating the steps you suggested.
Thanks so far.
I can't get Calculix CAE working whatsoever. Might be blatantly clear to someone, but not to me.
I always get the following error message as shown:
[notice] A new release of pip is available: 23.1.2 -> 23.3
[notice] To update, run: C:\Users\drppo\Documents\cae_20230122_v0.9.1\bin\python\python.exe -m pip install --upgrade pip

Something went wrong.
Could you please shed some light on it?
Thanks
