Running from source Anonymous 12/01/2018 (Sat) 20:56:00 Id: c4a924 No. 10837

I'm having a lot of trouble getting hydrus to run from source. Could not import lz4. I have lz4 installed.

Traceback (most recent call last):

ImportError: pafy: youtube-dl not found; you can use the internal backend by setting the environmental variable PAFY_BACKEND to "internal". It is not enabled by default because it is not as well maintained as the youtube-dl backend.

I have youtube-dl installed as well. Setting the PAFY_BACKEND fixes this.

I have no idea what to do here. Any help appreciated. Thanks.

Hey, thank you for this report. I think you have an unlucky older version of the client here. My recommendation is to update to a more recent version. More specifically: lz4 started having trouble importing recently in a variety of situations, I am not sure why. I put some time into it but couldn't figure it out and will revisit it in the new year when I am on python3. It is not required. pafy and youtube-dl shouldn't be a big deal either, but I guess the new version complains if it is missing. I think you can fix this on the python end by installing 'pip install youtube-dl', which I guess adds some python bindings to youtube-dl and is actually what pafy is looking for here. Pafy (which does some borked youtube downloading) is only needed for some experimental code, so I will change the code to no longer dump out if import fails. The ordered_dict issue turned up a few weeks ago, when requests updated and could no longer unpickle (load from a serialised object) its sessions. The code in newer versions should recover from this error and regenerate empty sessions for you this one time. Please let me know how you get on.

>>10843 I was afraid of updating as my hydrus db has surpassed my backup drive in size. I updated to 332 (from 317) anyway, everything went fine phew. Running from source now yields this error:

Could not import lz4--nbd.

>>10861 I removed the _ssl.pyd file that comes with the hydrus installer and it seems to be working after doing that. Same thing for the lz4*.pyd files. No more import errors.

>>10875 Great, I am glad you figured this out. Let me know if you encounter any more problems.
