here's what I get from the console

If I comment out the YDK import and ydk generator function from the adapter it appears to work fine. I can't find where to install appmaker. It would be nice to have but not critical to my use today.

I have the same issue. I also don't see where app_maker has ever been associated with the ydk library. Where is this supposed to be loading from?

Have you run setup.sh? It should have installed ydk library. See here

[jmcgill298]

yes

If you have run this script, looks like it creates a virtualenv in a directory named “v” where it installs everything. Can you try activating this virtualenv using a command something like the below?

source v/bin/activate

Then, you can check if ydk is installed using the below command:

pip list|grep ydk

After the above, can you try logging in again?

[jmcgill298]

I will have to completely reinstall it, at this point I have already cleaned it up

[jmcgill298]

reinstalled and the same issue.

(netconf) >ls v/lib/python2.7/site-packages/ | grep ydk
ydk
ydk-0.6.3.dist-info
ydk_models_ietf-0.1.4.dist-info
ydk_models_ietf-0.1.4-py3.5-nspkg.pth
ydk_models_openconfig-0.1.4.dist-info
ydk_models_openconfig-0.1.4-py3.5-nspkg.pth
ydk_.so

Again, I don't see where app_maker exists; where should this be importing from?

Looks like you have ydk 0.6.3 (latest version) installed somehow.

But, setup.sh installs older 0.5.4 version which has app_maker module.

Can you please uninstall and reinstall as below:

pip uninstall ydk ydk-models-cisco-ios-xr ydk-models-ietf ydk-models-openconfig

git clone https://github.com/CiscoDevNet/ydk-py.git -b yam; \
cd ydk-py; \
cd core; \
python setup.py sdist; \
pip install dist/ydk*.gz; \
cd ../ietf; \
python setup.py sdist; \
pip install dist/ydk*.gz; \
cd ../openconfig; \
python setup.py sdist; \
pip install dist/ydk*.gz; \
cd ../cisco-ios-xr; \
python setup.py sdist; \
pip install dist/ydk*.gz; \

If you look at the path in my output you will notice those are the ydk packages in the v virtualenv created by the bash script. The bash script does not install 0.5.4, but actually a branch of version 0.5.5 (which does work). The problem is that installing the models actually causes ydk to upgraded to the latest version. I re-installed from ydk-py/core and it did allow the login.

I'm seeing the same issue. As long as you don't upgrade the models, yang-explorer will start. However, if you subsequently run setup.sh, the latest ydk is installed because of the most recent model dependencies. This is a problem since you'll want to use the latest models for your IOS platform. If you make the mistake of running ./setup.sh, the ydk build wheel fails and you'll receive the app_maker error as noted by the OP. You have to run the script/steps above from abhikeshav to downgrade ydk and the models. Lather, rinse, repeat. :-)

Is there a fix for the dependency of ydk < v0.7.1?
