kandi X-RAY | qtpy Summary

qtpy is a Python library typically used in User Interface, Animation, Qt5 applications. qtpy has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can install using 'pip install qtpy' or download it from GitHub, PyPI.

QtPy is a small abstraction layer that lets you write applications using a single API call to either PyQt or PySide. It provides support for PyQt5, PyQt6, PySide6, PySide2 using the Qt5 layout (where the QtGui module has been split into QtGui and QtWidgets). Basically, you can write your code as if you were using PySide2 but import Qt modules from qtpy instead of PySide2 (or PyQt5).

            Looking at the strace output for both root and greg, the problem seems clear.

            For the root user, python 3.6 finds the libraries in /usr/lib64/python3.6.

            However, for greg, it only looks under /usr/bin/python3 for subdirectories. That doesn't work because /usr/bin/python3 is a file.

            I suspect that the user greg has PYTOHNHOME set erroneously to the location of the Python binary , and that is causing the issue.

            Remove PYTOHNHOME from your environment, log out and log in again.

            Note: the stuff below is probably barking up the wrong tree. I'll leave it for information.

            The encodings module is an (undocumented) part of the python standard library. It is used by the locale module.

            Based on the output I suspect that your Python installation has been damaged or corrupted. Try re-installing python.

            EDIT:

            If a forced re-install doesn't fix the problem, check that the directory encodings exist in your Python stdlib directory, and is accessible for all users.

            Asked 2022-Mar-13 at 16:13

            I am trying to build an app from a python file (Mac OS) using the py2app extension. I have a folder with the python file and the "setup.py" file.

            • I first tested the app by running python setup.py py2app -A in the terminal and the dist and build folder are successfully created and the app works when launched.
            • Now when I try to build it non-locally by running the command python setup.py py2app in the terminal, there are various "WARNING: ImportERROR" messages while building and finally a error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib' error.

              How can I fix this? I've tried to delete anaconda fully as I don't use it but it seems to still want to run through it. Additionally, I have tried to run the build command using a virtual environment but I end up having even more import errors.

            The error error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib' was caused by py2app trying to build the program bundle using a non-existent interpreter. This means that even if you try to uninstall a manager like Anaconda, it still has option logs somewhere on your mac.

            The fix:

            1. Open the terminal and type the command type -a python.

            So in case anyone comes across similar for any reason with me encountering this probably due getting a new machine and IT doing their voodoo magic transferring my old stuff to this new machine.

            Anyhow, there were a bunch of things I still needed to install after I got my new machine and i am not able to exactly pin point what caused issues from my question but in the end I was able to resolve. Follow me there below ...

            Checking out my python.exe files I found 2 paths. First one added as environment variable

            1. C:\Users-----\AppData\Local\Programs\Python\Python310
            2. C:\Users----\AppData\Roaming\Python\Python310\

            Second one not added. Adding roaming version to path variables did not solve the issue and gave additional errors instead: Fatal error in launcher: Unable to create process using '"C:\Program Files\Python310\python.exe"

            So

            1. I uninstalled python (done that before didnt help doing just that alone)

            2. Deleted all environment variables pointing to python (here is what environment variables are just in case - https://www.computerhope.com/issues/ch000549.htm)

            3. Uninstalled python extension from VS code (https://marketplace.visualstudio.com/items?itemName=ms-python.python)

            4. Deleted Python folders mentioned in the two paths above

            5. Then reinstalled python (clicked add to path during installation)

            6. Reinstalled VS code python extension

            7. Everything works now.

            applaunchservices appears to be Apple-only:

            Simple package for registering an app with apple Launch Services to handle UTI and URL. See Apple documentations for details.

            I suspect you don't need that, either. Did you create your requirements.txt from a pip freeze? There's likely a bunch of stuff in there you don't need.

            I suggest you review that file and remove anything you aren't directly depending on. pip will find transitive dependencies (dependencies your dependencies depend on) and install them automatically.

            Prune that file, commit, and redeploy.

            "(Not Responding)" in Windows is usually the consequence of a deadlock. Historically, a lot of confusion has surfaced over whether to override run() or to use moveToThread() when dealing with QThread:

            1. You're doing it wrong...
            2. You were not doing so wrong
            3. QThread documentation: do not discourage the reimplementation of QThread

            Though both methods are accepted, I chose to use moveToThread() because I learned it was best used when you have threads that need to interact with one another through signals and slots (see QThreads: Are You Using Them Wrong?)

            Looks like this is part of an actively tracked issue with Tkinter in PyCharm. You can find the reference on the Pycharm's developer's issue tracker. The issue is undiagnosed, but if looking at similar problems with Tk on StackOverflow, one can see that it's an issue with thread safety and/or multithreading.

            All I can do is speculate as to the cause, which is not helpful, however, I can at least collate the suggested workarounds:

            1. Switch to a different Matplotlib backend (See docs: What is a backend?). Such as Qt5, but you will need to make sure they are available in your environment.

              This approach is the most promising as other backends are better able to deal with not being the main thread or are explicitly safe for multi-threading. It's also the simplest unless you have a really specific reason for preferring TkAgg.

            2. Do not use the debugger with interactive plots.

            3. Set "Variables Loading Policy" to "Synchronously" in Debugger as suggested by a PyCharm dev in the linked issue.

            4. Enable "Scientific mode" in Pycharm.

            5. More esoteric workarounds such as closing your figures within the code before drawing the second one. Example, after plotting the first figure:

            Try to use some other version of ipython.

            Replace the python version in your requirements.txt with:

            ipython==7.24.1

            However, it doesn't have anything to do with docker configuration i.e. --network=host

            • have noted that your data is on kaggle, so start by sourcing it
            • there really is only one issue shapely.geometry.MultiPoint() constructor does not work with a filtered series. Pass it a numpy array instead and it works.
            • full code below, have randomly selected a point to serve as gpdPoint
