When I use “world.load_all()” with lilv.py . I’m getting errors as given below .
lilv_world_load_file(): error: Error loading file `file:///sbin/mkfs.bfs/manifest.ttl’
lilv_world_load_bundle(): error: Error reading file:///sbin/mkfs.bfs/manifest.ttl
error: failed to open file /sbin/mount.nfs/manifest.ttl (Not a directory)
can anyone please help me to sort it out ?
If you’re trying to use this with MODEP, try setting this environment variable before running your script:
export LV2_PATH=/var/modep/lv2:/var/modep/lv2-presets
Thanks sir, it works . Thanks a lot . 
I’m experimenting with mod-host and lilv.py without mod-ui on a clean 64bit raspberry os .
Then, I get these errors :
error: failed to open file /home/pi/.lv2//Base/manifest.ttl (No such file or directory)
lilv_world_load_file(): error: Error loading file `file:///home/pi/.lv2//Base/manifest.ttl’
lilv_world_load_bundle(): error: Error reading file:///home/pi/.lv2//Base/manifest.ttl
does it occur for the same problem ?
Does it matter that you have a “//” in the path? Just guessing.
I too am experimenting with lilv.py on a MODEP setup. Lots of information returned through that API!
no, there is no “//” path
I guess there is some another problem . not sure . let see .
Yeah, Modep is great
You mean in the above path? After .lv2?
Ohh sorry, I didnot notice . I rectify will this .
No luck,
error: failed to open file /home/pi/.lv2/Base/manifest.ttl (No such file or directory)
lilv_world_load_file(): error: Error loading file `file:///home/pi/.lv2/Base/manifest.ttl’
lilv_world_load_bundle(): error: Error reading file:///home/pi/.lv2/Base/manifest.ttl
same error
What is the code you’re running that gives you this error?
I’m getting this error when I started mod-host also .
error: failed to open file /home/pi/.lv2/Base/manifest.ttl (No such file or directory)
lilv_world_load_file(): error: Error loading file `file:///home/pi/.lv2/Base/manifest.ttl'
lilv_world_load_bundle(): error: Error reading file:///home/pi/.lv2/Base/manifest.ttl

When I’m using PedalPi-PluginsManager library .
Do you have the LV2_PATH variable set? Modep’s .lv2 plugins should not be interested in anything outside of /var/modep/lv2*.
Yeah I set /home/pi/.lv2 as LV2 Path
What are you trying to do?
I’m trying to build my own hardware based mod-host and jack with python . And trying to make it like HeadRush Processor . 
Ok, in that case the errors you receive are something specific to your particular working/development environment.
Sir, when will you release Modep for 64 bit system ?
Thanks Sir, for your support
