Python Error

[LM]

Hi All,

I've got Python installed on my Windows machine (2.7.11) and now trying the Python nodes (I'm new to Python though so please bear with me).

I'm running a code to construct the RDKit bit vector object as below:

from rdkit import DataStructs
for fps in input_table['Fingerprint']:
	fp = DataStructs.CreateFromBitString(fps)

However, I got this error here:

Traceback (most recent call last):
  File "C:\Program Files\KNIME\plugins\org.knime.python_3.1.2.v201603040957\py\PythonKernel.py", line 282, in execute
    exec(source_code, _exec_env, _exec_env)
  File "<string>", line 6, in <module>
ArgumentError: Python argument types in
    rdkit.DataStructs.cDataStructs.CreateFromBitString(unicode)
did not match C++ signature:
    CreateFromBitString(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >)

Does anyone know if there's anything that I did wrong with the installation?

Thanks.

LM.
