Pythonista 3 + StaSh + Plotly... I'm Close to a meltdown.

Hi! maybe this qustion wasn't meant for me but I would love it to work in either case. :) -

On the phone I still get a fsi, man, patches in stash_extensions that are empty... bin is also empty.
Do not worry about these folders. They are meant for extensions and are empty by default. In fact,
stash_extensions/bin/is the only one of these folders which is actively used (pipinstalls commands here).I'ts an example I found in a tutorial and I have replaced username and token for my own when I run it.
I just tested this example on both py2 and py3 and it seems to work (I get some warnings that
plotly.graph_objs.Datais deprecated and also an error message that there is no account for[username](obviously), but it imported and executed fine). I had to installdecoratorandretryingand also restart pythonista a few times.This generated the following traceback:
Have you tried restarting pythonista (double tap home, the force-quit the app and start again)? Pythonista caches imports, which sometimes leads to weird issues and old imports. You should always restart pythonista if you installed a package to fix an 'ImportError` (or something related).
If I run my darksky-app, (that I for sure can have broken myself!) it doesn't seem to get 'core'?
Same as above (btw, import works fine for me, but i have not tested actual functionality).
BTW, you should avoidfrom module import *-style imports, as they may lead to import-related problems. A better import would befrom darksky.core import *.
If you are interested in an explanation: As @JonB said,sys.pathis modified when a script is executed. This means that python search for imports in a different order depending on the executed script and your CWD. For example, if you would execute/importdarksky/__init__.pyfrom within thesite-packages/stash-repository,import corewould importstash.coreinstead ofdarksky.core. This would lead to problems or unexpected behavior.Python 3.6.1
The py3 version of StaSh is still a bit experimental, so there may be more errors compared to py2. That being said, everything above should work fine (i tested your example on both py2 and py3 and darksky on py2) .
I did upgrade per instructions of @bennr01 : selfupdate -f bennr01:wheelfix
DarkSky worked when I installed this before, without the wheelfix-upgrade.Is there a
core.py-file insite-packages-3/darksky/? If there is, then you are probably experiencing some of the CWD-related problems mentioned above. I can confirm that theno module named 'core'error exists depending on the way you import/launch__init__.pyYou should either try it withfrom darksky.core import *instead or try to install and run with py2 (py2 has some different import behaviors andfrom darkskye import forecastworks fine). Also, restart after any changes to files in asite-packages*directory, or your change will not take any effect. -

Ok!

Wow. I cannot get it to work. :/
Have you tried restarting pythonista (double tap home, the force-quit the app and start again)?
I have restarted the app countless of times, exactly that way. Last try of installing Plotly, Pythonista couldn't reopen again, it crashed while loading. But hey, I didn't have to restarting it?
Same as above (btw, import works fine for me, but i have not tested actual functionality).
Wow again. I will have to give this another go!
BTW, you should avoid
from module import *-style imports, as they may lead to import-related problems. A better import would befrom darksky.core import *.I changed this part of the code, restarted again and again but it still won't run. I tried to remove darksky from Python Modules/site-packages-3 where I removed the darksky-folder. I did about 10 restarts of the app and then tried to reinstall through StaSh; "Error: Package is already installed"
I did a reinstall of pythonista but I don't feel like trying to get this Plotly to work anymore. I would be so happy if the scripts I had could just work as they used too..Is there a
core.py-file insite-packages-3/darksky/? If there is, then you are probably experiencing some of the CWD-related problems mentioned above.Yep there was before I reinstalled it all over again. The change to
from darksky.core import *didn't make any difference unfortunatly. And thank you and @JonB for explaining how the sys.path works!I can confirm that the
no module named 'core'error exists depending on the way you import/launch__init__.pyYou should either try it withfrom darksky.core import *instead or try to install and run with py2 (py2 has some different import behaviors andfrom darkskye import forecastworks fine). Also, restart after any changes to files in asite-packages*directory, or your change will not take any effect.I tried installing darksky with StaSh running python 2.7. It was installed. Restarted the app a couple of times. Ran the script with python 2.7, I get an error with the syntax, fair enough, though it doesn't print the traceback, I get an empty console. Regardless if I use
from darksky import forecastorfrom darksky.core install *I get the same result.I guess that's as far as I can manage to get with this.. can I use a js-based graph-tool in Pythonista? If you have any suggestions for this I will gladly listen.
-
Sorry, is darksky your own repo? And you installed with pip? Can you provide the pip commands you used?

@JonB
Thank you!!
I actually wrote an answer along "I usedpip install darkskyand lalala", the second I clicked [Submit] I realized I have been writing darksky instead of darkskylib... installing the ****** wrong library. š³ š« šThe library: https://github.com/lukaskubis/darkskylib
It's not my own, and it actually doesn't say how to install it in the readme. I have just assumed..So I found the reason, I thought..! On the ipad air 2, that had a clean install of pythonista...
- I installed stash, restarted app.
pip install darkskylib, restarted app.pip install requests, restarted app.- Ran the script: "Cannot find module for chardet.
Which I thought was strange but I realized I didn't update stash this time around. So I did
selfupdate -f bennr01:wheelfix. Tried again, same thing.- I removed all the files I could find for darkskylib.
- I restarted pythonista.
- Ran
pip install darkskylibagain, it said it was already installed.
Did a full reinstall of the pythonista. New round.
- Install stash. restart app.
- Update stash, restart app.
- Install requests, restart app.
- Install darkskylib:
[~/Documents]$ pip install darkskylib <class 'ModuleNotFoundError'>: No module named 'chardet' [~/Documents]$ pip install chardet <class 'ModuleNotFoundError'>: No module named 'chardet' -
Is there a reason you need the latest requests, vs the one built into pythonista?
You need to check site-packages, site-packages-3, and site-packages-2, and remove (via file browser menu in pythonista, under Modules) requests, chardet, and idna folders, if present. Then force quit pythonista.
Then import requests should work.
Then, pip should be working again.
If you need new requests version, you could try
pip install idna
pip install chardet
pip install requestsI have not tried this with the current stash version... A safer approach might be to use pip download, then manually unzip/untar and copy the folders manually.
-
I finally got around to trying this on the latest stash. @bennr01, it seems the issue is that pip is not detecting doendencies using the whl.
Because of this, it is necesary to manually instal each dependency:
rm -f site-packages*/requests rm -f site-packages*/chardet rm -f site-packages*/idna pip install requests pip install chardet pip install idnaDo this all before running any other pip commands after starting the app.
The last three must be done within a single sesson.
Then force quit pythonista. import requests, and all should be happy.@bennr01 here is the whl install, showing it couldnt find dependencies.

I will also say, that running pip install plotly with latest stash caused pip to install all of the plotly folders into site-packages-3, instead of the plotly folder, which totally borked pythonista, and it crashes immediately upon open, even with safemode and pythonista3://. could possibly be my fault for hitting ctrl-z during the process.
so... don't do that

There should be a fix in the dev branch of the main repo, or did the fix not work?

Thanks for the info, i will take a look at it.
This line looks interesting:Warning: could not find 'metadata.json', can not detect dependencies!.
Apparently the.whl-format is a bit more flexible than i tought... -
Not sure if this is related or if I should start another thread but the error Iām getting when installing plotly is related to installing the attrs dependency:

@headsphere You could try disabling wheels for the installation using
pip --verbose install --no-binary :all: attrs.
