[jake9wi]

Before submitting an issue to Github about SHARPpy, please follow the below checklist to ensure that your issue can be resolved quickly.

• No other issues either open or closed describe what I'm reporting.
• I have checked to see if my issue has been resolved in a new version of SHARPpy.
• I have filled out the below information in as much detail as possible using dates, numbers, directions, pictures, etc.
• I have checked the SHARPpy documentation to make sure I'm doing things correctly, and my problem doesn't exist between my monitor and chair.
• I have attached the log and config files from the ~/.sharppy folder. If no log files exist, I have run the program in debug mode (e.g., sharppy --debug).

The management team for SHARPpy is a small team of volunteers. Being as thorough as possible with your issue submission will help us help you!

Hi @jake9wi - thank you so much for providing this information and filling out the form! I'm able to help you pretty easily here. It looks like this is an issue where the qtpy library is anticipating Qt6 is available, and I haven't updated the conda recipe yet to account for that. Would you be able to show me your anaconda environment and the log files? Use the conda list command.

You may also find some success by telling SHARPpy to use Qt5, which can be done via export QT_API=PySide2 on Mac/Linux via the bash shell and setx QT_API "PySide2" on Windows.

[jake9wi]

I tried setting the env variable as suggested and got the same traceback.

[jkrasting]

I am experiencing the exact same issue as well.

[skovic]

I was able to reproduce this problem by installing SHARPpy via conda and then running SHARPpy via "conda run sharppy".

@jake9wi and @jkrasting - I got past this problem by installing an older version of qtpy (version 1.10.0). You can install version 1.10.0 of qtpy by executing the following command in your conda environment:

conda install qtpy=1.10.0

If you get prompted to proceed while installing the package, be sure to enter y to proceed. When the install of the older qtpy is finished, try running SHARPpy again.

[jkrasting]

Thanks @skovic - I tried this. It no longer throws an exception, but it just hangs on startup.

(FYI - I am on an Intel Mac running MacOS Monterey)

[skovic]

@jkrasting If you look at the .sharppy subdirectory in your home directory, does sharppy.log have any error messages or exceptions present? Also if there is a sharppy-out.txt file, does it have any contents?

[jake9wi]

@skovic Setting qtpy=1.10.0 fixed it for me also.

[jkrasting]

@skovic -Nothing pops out at me. I've attached the sharppy.log file. I've also attached a picture of the hanging window and my conda environment. There is no sharppy-out.txt file.

conda_list.txt
sharppy_log.txt

.

[skovic]

@jkrasting Looking at the log file, I don’t think that the program is hung. I think what you have is a pop up window that is notifying you that there is a new version available (see log message below); it’s just that the window hasn’t rendered properly.

022-01-12 08:10:11,609 /Users/krasting/miniconda3/envs/sharppy/lib/python3.7/site-packages/runsharp/full_gui.py main Line #: 1212 INFO A newer release of SHARPpy was found on Github Releases.

I see this same message on my Windows 10 system until I select one of the options on the pop up window.

Try this:

1. Run SHARPpy.
2. When this blank window appears, press the enter key on your keyboard.
3. On my machine, this opens up my browser taking me to the site to download a new version.
4. Wait a min or so, and SHARPpy eventually opens up.

If you still get a blank window it probably means that there is some sort of incompatibility between your version of Mac OS and one of the conda/python packages.

[jkrasting]

Thanks. I tried hitting “enter”, but it didn't work. I have the spinning rainbow wheel in MacOS, so it appears to be hung.

[keltonhalbert]

@jkrasting I've been trying to track down this issue myself. It looks like MacOS requires an extra environment variable. A temporary fix is to set this environment variable in the shell before executing SHARPpy.

export QT_MAC_WANTS_LAYER=1

I'm working on a pull request to fix this issue more permanently.

[jkrasting]

Nice find! I’ll give it a try …

[jkrasting]

@keltonhalbert - I can confirm this temporary fix works
