• Install python's 'albumentations' in Kaggle's R kernel ?

  22 avril 2022, par dfrankow

  I can start an R kernel on Kaggle, run

  


  library(reticulate)
py_install('albumentations')


  


  Works for awhile, then finishes.

  


  However, importing it produces an error :

  


  reticulate::import('albumentations')


  


  


  Error in py_module_import(module, convert = convert) : ImportError : libopenh264.so.5 : cannot open shared object file : No such file or directory

  


  


  This looks like this stackoverflow question.

  


  The problem seems to be in ffmpeg, but I'm not sure what or how to install something to get that library.

  


  Below is ldd output of ffmpeg, showing the library is not found.

  


  conda_update doesn't help.

  


  system2("which",
        args=c('ffmpeg'),
        stdout=T, stderr=T)


  


  


  '/root/.local/share/r-miniconda/envs/r-reticulate/bin/ffmpeg'

  


  


  system2("ldd",
        args=c('/root/.local/share/r-miniconda/envs/r-reticulate/bin/ffmpeg'),
        stdout=T, stderr=T)

• Matomo 2 reaches end of life soon (December 2017), update now !

  7 décembre 2017, par Matomo Core Team — Community

  In less than three weeks, Matomo (Piwik) 2 will be no longer supported. This means that no further (security) updates will be released for this version. As per our Long Term Support announcement, Matomo 2.X is supported for 12 months after the initial release of Matomo 3.0.0 which was on December 18th 2016. Therefore, Matomo 2 will no longer receive any updates after December 18th 2017.

  It has been almost a year since we released Matomo (Piwik) 3 and we highly recommend updating to Matomo 3 ASAP. The major new release came with a new UI, performance and security improvements. If you are still on Matomo 2, the security improvements alone should be worth updating your Matomo to Matomo 3 now. We cannot recommend this enough.

  The update to Matomo (Piwik) 3 should be smooth, but may take a while depending on the amount of data you have.

  • If you have any problem with the update, feel free to get in touch with us, or ask in the forums.
  • If you are currently using Matomo (Piwik) self-hosted and would like to be upgraded, plus your Matomo managed in the official Cloud-hosted service, contact InnoCraft Cloud and they will migrate your database.

  At Matomo (Piwik) and InnoCraft, the company of the makers of Matomo, we have seen many thousands of Matomo installations upgraded over the past year and look forward to an exciting future for Matomo 3 and beyond !

• FFmpeg.AutoGen example of how to split audio file

  7 mars 2018, par Sven

  I want to use the FFmpeg.AutoGen project from here : https://github.com/Ruslan-B/FFmpeg.AutoGen

  I’m not familiar with the ffmpeg API, so I wanted to get an example of how to split an audio file into little files, for example the audio file is about 2 hours long (can be mp3,ogg,wav,etc.) and I want to split it into several little files of x minutes. The splitting should be done on the main audio file with timestamps from and to, for example from = 00:25:00 (meaning 25 minutes), to = 00:31:12 (meaning 31 minutes, 12 seconds) and the output should be the section from the main audio file, the result is 00:06:12 (meaning 6 minutes, 12 seconds) long.

  How can this task be achieved with the project ? Also a C example can help me, I would try to convert it into the framework.

  Thanks for your responses.
