Thanks. One more thing, on theano I'm guessing MKL is required to be installed onto each host that would use it at runtime? So I'd need a licensed copy for each host that will execute the code? I'm guessing that because theano needs to compile code at runtime. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
