Win 10 x64，conda，theano 0.9，python 3.6.1，spyder 3.1.4，IPython 6.0.0 當我在掃描API中測試代碼教程Iterating over the first dimension of a tensor: Calculating a polynomial，即當我在theano掃描api指南中運行示例代碼時發生了一些錯誤
import theano
import numpy as np
import theano.tensor as T
from theano import In
coefficients = theano.tensor.vector("coefficients")
x = T.scalar("x")
max_coefficients_supported = 10000
# Generate the components of the polynomial
components, updates = theano.scan(fn=lambda coefficient, power, free_variable: coefficient * (free_variable ** power),
outputs_info=None,
sequences=[coefficients, theano.tensor.arange(max_coefficients_supported)],
non_sequences=x)
# Sum them up
polynomial = components.sum()
# Compile a function
calculate_polynomial = theano.function(inputs=[coefficients, x], outputs=polynomial)

因爲其他的代碼運行良好，似乎theano.function引起的問題。儘管我嘗試使用In（）將測試值添加到係數和x，但問題也在那裏。
