| -Windows 7 64-bit Ultimate host, Virtualbox version 4.24 | |
| - Ubuntu Desktop 12.10 64-bit from ubuntu.com 7:30PM 2012-11-02 | |
| - installed following (I realize some of these have nothing to do with running these libraries, but I wanted to include anything in case something sticks out to you guys) | |
| - hg | |
| - git | |
| - dropbox | |
| - keepass | |
| - chromium | |
| - vsftpd | |
| - build-essential | |
| - ffmpeg (including ln -s .......en-ffmpeg) | |
| - python2.7-dev | |
| - python-setuptools | |
| - sudo easy_install pip | |
| - sudo pip install numpy | |
| - created new ssh keys | |
| - confirm "import numpy" works | |
| - confirm en-ffmpeg works | |
| - git clone https://github.com/echonest/remix.git | |
| - cd remix | |
| - git submodule update --init (appeared to check out the most recent, starts with 73046e...") | |
| - added my API key to .bashrc and confirmed it was set properly | |
| - sudo python setup.py install (from remix) | |
| - python test.py (which looks similar to the Step 4 - Make something beautiful example from http://echonest.github.com/remix/index.html#how except I used my own mp3, a filename called Rain.mp3 output to RainReverse.mp3, both in the same folder as test.py, which is two levels above remix github repo) | |
| Here's the output: | |
| karl@karl-VirtualBox:~$ python test.py | |
| en-ffmpeg -i "Rain.mp3" | |
| en-ffmpeg -y -i "Rain.mp3" -ac 2 -ar 44100 "/tmp/tmpUeMqCw.wav" | |
| Computed MD5 of file is d68d079a0cb2571ec693cbbe834a0b89 | |
| Probing for existing analysis | |
| Analysis not found. Uploading... | |
| Traceback (most recent call last): | |

| I'm happy to provide any more information that might help debug this. I'll also try some more things tomorrow. | |
