Hi all.

Got a new laptop and had to install Echo nest, Python, ect. again. Though I had it running on my old laptop, I had to follow the installation guide again. The laptop is running Windows 7 64 bit.

• Installed Python 2.6
• Installed NumPy
• Installed Echo Nest Remix and added both key and python to windows path.

When trying to execute any of the examples, I get an error. Here's the output from the command prompt:

C:\Python26\echo-nest-remix-examples\afromb>python afromb.py dafunk.wav pretend.wav dapretend.wav 0.9 env

pyechonest.util.EchoNestAPIError: Echo Nest API Error 6: An error occurred during analysis

No output file is generated, not even a temporary file in the Windows temp folder. I'm aware that the first Error 5 isn't critical. Been searching around for Error 6, but couldn't find anything.

Any idea of what I'm doing wrong? Thanks in advance!

dmorten - remix comes with its own version of pyechonest (there's a bit of version skew). Try installing the pyechonest that comes with remix to see if that helps. -- Paul

Thanks for your reply Paul.

Not quite sure what you meant though. I couldn't find anything "pyechonest" related in my install. I downloaded it, installed fine, I could start song.py and others - but then I got stuck.

I just downloaded Echo-Nest-Remix package again, installed it and afterwards I checked that the python and ffmpeg paths works.

I still get an error though. The two wave files are present in the same folder, so that's not the problem. Here's the output, a bit different than last time:

C:\Python26\echo-nest-remix-examples\afromb>python afromb.py dafunk.wav pretend.wav dapretend.wav 0.9

DMorten - Your best best is to head over to the Echo Nest Remix google group and post your query there. Remix is an open source project and is supported by the community via that forum.

Paul - I'll do that. Didn't realise that. Thanks for your time.
