1 SyntaxError: Missing parentheses in call to ‘print’

解決：python2支援 print “xxxx” ，python3需要使用print(“xxx”)

2 SyntaxError: multiple statements found while compiling a single statement

解決：多行程式碼直接在IDLE中編譯，是每行都要回車的，或者新建一個py檔案來執行。

3 ImportError: Could not find ‘cudart64_90.dll’.

ImportError: Could not find ‘cudart64_90.dll’. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable. Download and install CUDA 9.0 from this URL:

4 ImportError: No module named ‘utils’

解決：pip install utils

5 NameError: name ‘xrange’ is not defined

解決：Python3中xrange改為range

6 ImportError: No module named ‘input_data’

解決：解決：下載input_data或者使用tensorflow自帶的input_data
from tensorflow.examples.tutorials.mnist import input_data

7 ValueError: Cannot evaluate tensor using eval()

ValueError: Cannot evaluate tensor using eval(): No default session is registered
解決：根據提示新增引數sess（sess為自己定義的Session名稱）：

train_accuracy = accuracy.eval(feed_dict={x:batch[0], y_: batch[1], keep_prob: 1.0})  

修改為：

train_accuracy = accuracy.eval(session=sess,feed_dict={x:batch[0], y_: batch[1], keep_prob: 1.0})  
 

8 ValueError: Cannot execute operation using run()

ValueError: Cannot execute operation using run(): No default session is registered. Use with sess.as_default(): or pass an explicit session to run(session=sess)
解決：根據提示新增引數sess（sess為自己定義的Session名稱）

train_step.run(feed_dict={x: batch[0], y_: batch[1], keep_prob: 0.5}) 

修改為：

train_step.run(session=sess, feed_dict={x: batch[0], y_: batch[1], keep_prob: 0.5})
