Neural Net initialization failed

[franciscocarreno]

During installation I got an error. The path to download nnImplementationV2.zip from dropbox doesn't exits anymore.

Error:

Can you run git log inside your NTRTsim folder and post the results?

I'm assuming you're using something other than the master branch, as the master branch was updated a while ago to pull deps from http://ntrt.perryb.ca

In the meantime you can manually resolve this by doing a find and replace

Replace

NEURALNET_URL="http://dl.dropbox.com/u/18209754/Blog/nnImplementationV2.zip"

with

NEURALNET_URL="http://ntrt.perryb.ca/storage/dependencies/nnImplementationV2.zip"

Ahh, I see, presumably you're pulling that from the V1.1 tag on Github? Or maybe you downloaded that version directly from the NTRT site at nasa.gov?

In any case, you'll want to use the master branch version of NTRTsim. Version 1.1 is very old now, its last commit was on January 9th of 2015. Much has changed since then.

Here is a direct link to get the current master branch as a zip:

I was using V1.1. Using current master branch now!
I run setup again and got: "Boost initialization failed"

git log:
francisco@ubuntu:~/Documents/NTRTsim-master$ git log
fatal: Not a git repository (or any of the parent directories): .git

Boost initialization failed.txt

That is a known issue. Just run setup again (don't delete your existing install or anything) and it shouldn't give you that error the second time.

setup.sh finished successfully after second run. Thank you PerryBhandal!
I got a new error while running build.sh which I posted as new issue (#218)
