            CEFPython unable to embed inside pyqt5 application
            Asked 2021-Sep-03 at 07:55

            I am new to Cefpython and PyQt5 both. I have tried to follow the tutorial in the cefpython repository. I was trying to embed cefpython inside a pyqt application and haven't achieved any success, what's wrong here?



            Answered 2021-Sep-03 at 07:55

            The problem is that the QWindow used to render the browser is hidden. The solution is to create a QWidget using QWidget::createWindowContainer() and add it using a layout.

            Python 3, concurrent.futures.ProcessPoolExecutor and CEF crashes after pool size is reached
            Asked 2021-Aug-23 at 20:41

            I'm on Win 10 with Python 3.9.6 and am trying to create a concurrent.futures.ProcessPoolExecutor pool with a small size and add a lot of tasks to it which use CEF.

            This always works for the first tasks up until the pool size is reached and afterwards every future reports the exception



            Answered 2021-Aug-23 at 20:41

            CEF does not allow to call Initialize after calling Shutdown. See here for more info.

            When you have more tasks than worker processes, those tasks are queued to be executed later when a worker becomes available.

            The first 2 tasks run ok, because a new process is created for each one of them.

            The third task fails because it runs in a process that has already been used (i.e.: initialized).

            A quick fix would be to add a guard, for example:

            I have some simple cefpython code opening a url and am trying to create a stand alone executable with pyinstaller:

            I copied files from https://github.com/cztomczak/cefpython/tree/master/examples/pyinstaller to a a directry named pyinstaller

            I made following minor changes to pyinstaller.spec

            This is not really the answer I would like to accept, but it is at least one solution and contains information, that might lead to a better fix, a better answer.

            After debugging with strace I found out, that the executable searches many files like for example icudtl.dat, v8_context_snapshot.bin, locales/* were searched in 'dist/cefapp/cefpython3but were copied todist/cefapp/`

            Writing Python pip-able package: How to access files in the package?
            Asked 2020-May-15 at 21:34

            I'm trying to develop a visualization package based on CEFpython technology, so the function has to access an html file. So the structure of the package is basically:


            --> init.py

            --> main.py

            --> index.html

            and in the main.py file, I defined a function:

            Look at the documentation of pkg_resources.
            It has a method called resource_filename that you can use to get absolute path to any internal module.
