I am working on luna16 dataset, I use tensorflow CNN code to classify images (cancer/not-cancer [0 or 1]), the code has no problem and runs without any error, but in session when I want to add summary _, c, summary = sess.run([accuracy, cost, merged_summary], feed_dict={x_img: X, y_label: Y}) I get this error: InvalidArgumentError (see above for traceback): Expected dimension in the range [-1, 1), but got 1 [[Node: accuracy_5/ArgMax_1 = ArgMax[T=DT_FLOAT, Tidx=DT_INT32, output_type=DT_INT64, _device="/job:localhost/replica:0/task:0/device:CPU:0"](_arg_y_label_0_1, accuracy_5/ArgMax/dimension)]] if I remove the merged_summary the code is works fine?
