Digit 5.1 run error

[sigmoidx]

Hello?

I just built Caffe successfully (checked 'import caffe' in python) and ran the command

sudo -H pip install -r requirements.txt and it seemed to install everything without any problem.

but it shows some error when I run ./digits-devserver

KeyError: 300

I have no idea what causes the error. Thanks!

Looks like two of your installed Python dependencies have incompatible versions.

You're using conda, which means you've deviated from our official installation instructions. My guess would be that when you use sudo, it discards the conda environment and picks up a pip binary from outside your conda environment. You should never need sudo when using conda, as I understand it.

I have solved this! First I uninstalled lastest version of flask (maybe 0.11.0 version) then installed 0.10.1 version.

sudo -H pip install -I Flask==0.10.1

But the installed flask is located in /usr/local/lib/python2.7/dist-packages, so I moved them into

/home/oscar/anaconda2/lib/python2.7/site-packages then it works!!!!

Thanks!
