The question about Tensorflow about Incompatible shapes: [730,5] vs. [30,5]

[ghost]

im new for tensorflow,and while i am tring to run my Session,there is an error :

During handling of the above exception, another exception occurred:

and my input shape is [730,7],output shape is [30,5],
self.__out = tf.transpose(tf.add(tf.matmul(locals()['self.__hidden_' + str(self.__l_num)], self.__W_out), self.__bias_out)) self.__mse = tf.reduce_mean(tf.math.squared_difference(tf.transpose(self.__out), self.__Y)) self.__opt = tf.train.AdamOptimizer().minimize(self.__mse)
and i dont know how to fix it,thanks for the help
