Chianti TypeError in train.py l264

[uyekt]

Hi there,
I'm really interested in using your network and performance does matter, that's why I installed chianti.
However I get this error:

python predict.py --architecture frrn_a --model_file models/frrn_a.npz --cs_folder ../Datasets/cityscapes_lk

TypeError: No registered converter was able to produce a C++ rvalue of type std::__cxx11::basic_string<char, std::char_traits, std::allocator > from this Python object of type str

I'm using python 2.7 in Anaconda. I have all dependencies. Boost version is 1.64. I tried different version of boost / boost-python and still got the same error. Any clue?

Hm, this a weird error. It says that it cannot produce a C++ string from a Python string, which is something it should be able to do. I'll have a closer look on Sunday. Thanks for reporting this.

@TobyPDE did you had time to took a look, where it could come from?
