Closed zenetio closed 6 years ago

zenetio commented 6 years ago

The code is firing an error when it tries to save the map to disk.

Can you show me the error? And are you using the workspace or the supplied VM?

zenetio commented 6 years ago

I tried in both VM and workspace and the error is the same. ![image](https: error //user-images.githubusercontent.com/578337/36929715-aae8fb5e-1e73-11e8-99cd-

To check the code I added a show() before save and the picture was displayed correctly. But fails trying to save().

Thanks for sharing. Not sure why you are getting this or how I can replicate this error but I try in both VM and workspace and it both worked. I am afraid you are deleting the Images folder itself. Can you try these and let me know if you get it working?: $ cd Downloads/ $ git clone https://github.com/udacity/RoboND-OccupancyGridMappingAlgorithm $ cd RoboND-OccupancyGridMappingAlgorithm/ $ rm Images/* $ g++ solution.cpp -o app -std=c++11 -I/usr/include/python2.7 -lpython2.7 $ ./app

Fixed the issue.

karimchamaa commented 6 years ago

Still curious to know why you were getting the error?

zenetio commented 6 years ago

There was a syntax error in the Image name string passed to save() function. To avoid this I should have tried the solution.cpp before open an issue. Tks.
