theano.functionでのエラー

Question

プログラミング初心者です． 
深層学習に関して勉強しようと思い, 試しに theano を使った非常に短いコードを動かそうとしたところエラーが出てしましました．

y = x ** 2
f = theano.function(inputs=[x], outputs=y)

試したこと

numpy と theano を入れ直しましたが直りませんでした．

補足情報（FW/ツールのバージョンなど）

以下はバージョン情報です．

Python 3.6.0
numpy 1.16.1
theano 0.9.0

Answer 1

numpyとtheanoのバージョンによっては、互換性が無いことでエラーが起こる可能性があります。

以下の環境では動作するので、バージョンを指定して再度インストールしてみてはいかがでしょうか。

numpy 1.16.3
theano 1.0.4
