Unable to create dataset.

[Skylion007]

I am trying to get this example running, but unfortunately, I have run into a little bit of a snag. I keep getting this error when I attempt to run create_database.sh

File "scripts/create_dataset.py", line 122, in create_patches
    key = b'%010d' % keys[n_patches]
TypeError: ufunc 'remainder' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

Any ideas on how to proceed?

Could you tell me your environment (OS, versions of python and all related packages)?

A Docker container I wrote to run this project running on CentOS. I can do you one better and provide the dockerfile if you want.

See #5 for the Dockerfile.

I have narrowed down the error. It is caused when you attempt to create the dataset for roads or roads_mini, buildings or merged. All --single and --multi work fine.

Found the bug! It was a very obscure feature in Python3.5 called bytestring formatting. For ease of deployment, I was using Python 3.4 since Ubuntu 14.04 hadn't migrated over yet so the feature wasn't supported. Luckily you can backport it by replacing the line with this little hack.

key = bytes('%010d' % keys[n_patches], 'ascii')
