error when running the example

[qjqjqjj]

Hi,

I follow the post and installed the stuff that is needed for this example, however when I run it at jupyter it has the following error:

---

25 finally:
26 fp.close()

ImportError: /usr/local/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so: undefined symbol: PyUnicodeUCS4_AsUTF8String

can someone do enlighten me? I just started learning using SiameseNet and jupyter so am not sure whats the error and how to slove it.

Thanks

It looks like keras is having trouble importing tensorflow. Make sure you have a working version of tensorflow, installed on the same version of python(2 vs 3) you're using in the jupyter notebook.
