Needs some thinking on how best to approach this as tstickers supports multiple backends

For now, try the following:

pip install tstickers[rlottie-python]

difhel commented 5 months ago

@FredHappyface I tried this, still the same error.

Ah that's no good. I'll take a look at this as soon as I've some free time!

I think this is an unrelated issue connected with caching, as I often encourage it when redownloading packs. After I used rm -rf ./downloads, I encountered another issue:

that's work for me ,thx :+1:

TomerGamerTV commented 3 months ago

Its working but its failing to convert anything

Edit: After letting it run for a while it seems like for some reason it does convert some sticker packs but doesn't others..

HaiLinWang commented 2 months ago

Check the pyrlottie documentation does not support the darwin_x86_64 and darwin_arm64 .conversion stickers can specify rlottie-python or pyrlottie You can use rlottie-python to try the conversion. For example, python -m tstickers --backend rlottie-python

FredHappyface commented 2 months ago

Hey taking a look at this today to make this all a bit more user friendly! Now the tstickers package will install with pyrlottie regardless of the extra chosen. Bit frustrating that python doesn't handle this particularly nicely. Also the cli will provide a more helpful error message in the case of using an uninstalled backend. For example in testing

$ tstickers -b rlottie-python
ERROR    | !! rlottie-python is not installed! Install with "pip install rlottie-python"

Apologies this has taken so long to get around to! I'll have a look at the pyrlottie lib later to see what I can do around the darwin support. Broadly the lottie-python lib has broader os support than this lib but seems to be a little less performant as a backend (due to the use of python-pillow oddly)

I'll also write some documentation on this as I realise it's a bit broken and confusing at the moment (also fixing as much of the broken as possible)

FredHappyface commented 2 months ago

@FredHappyface I tried this, still the same error.

Hmm really strange. Ive tested locally and I suspect this is largely down to unclear documentation as things behave largely as expected. Ie

PS C:\Users\Dell> py -m venv venv
PS C:\Users\Dell> .\venv\Scripts\activate.ps1
(venv) PS C:\Users\Dell> py -m pip install tstickers[pyrlottie]
...
Installing collected packages: win32-setctime, urllib3, typing-extensions, six, platformdirs, Pillow, packaging, numpy, idna, colorama, charset-normalizer, certifi, attrs, url-normalize, requests, loguru, emoji, deprecation, cattrs, requests-cache, pyrlottie, tstickers
...

stickers -b pyrlottie works as expected

stickers -b lottie-python throws an error

As noted above, I've changed the default install to include pyrlottie going forwards (releasing later today) so not specifying a backend will work on a vanilla install :)

Hi can you create a new issue for this? And can you provide the link to the sticker pack not working/ or a stacktrace so I can investigate this? Thanks :)
