# 十、從 tf1.12 轉換為 tf2 Google 提供了一個名為 `tf_upgrade_v2`的命令行腳本，該腳本會將 1.12 版文件（`.py`和`.ipynb`文件）轉換為 TensorFlow 2 兼容文件。 此轉換的語法如下： ```py tf_upgrade_v2 --infile file_to_convert --outfile converted_file ``` [這里是更新腳本的實戰演示](https://www.youtube.com/watch?v=JmSNUeBG-PQ&list=PLQY2H8rRoyvzoUYI26kHmKSJBedn3SQuB&index=32&t=71s)，以及有關它的更多詳細信息，請參見[這里](https://github.com/tensorflow/docs/blob/master/site/en/r2/guide/upgrade.md) 。 重要的是要注意，在運行腳本之前，不應該*手動更新*代碼部分。 該腳本不會解決所有問題，但是它生成的報告將標識那些必須手動解決的問題。 特別是，`tf.contrib`已從 TF2 中刪除，因此必須跟蹤并手動修復以前駐留在其中的函數。 這是腳本生成的報告的示例： ```py Processing file 'Chapter1_TF2_Snippets.ipynb' outputting to 'Chapter1_TF2_alpha' -------------------------------------------------------------------------------- 37:4: INFO: Added keywords to args of function 'tf.size' 48:13: INFO: Added keywords to args of function 'tf.transpose' 74:0: INFO: Added keywords to args of function 'tf.reduce_mean' 75:0: INFO: Added keywords to args of function 'tf.reduce_mean' 76:0: INFO: Added keywords to args of function 'tf.reduce_mean' 77:0: INFO: Added keywords to args of function 'tf.reduce_mean' 78:0: INFO: Added keywords to args of function 'tf.reduce_mean' 110:4: INFO: Added keywords to args of function 'tf.argmax' 114:4: INFO: Added keywords to args of function 'tf.argmin' 121:4: INFO: Added keywords to args of function 'tf.argmax' 123:4: INFO: Added keywords to args of function 'tf.argmin' 127:4: INFO: Added keywords to args of function 'tf.argmax' 129:4: INFO: Added keywords to args of function 'tf.argmin' 136:0: ERROR: Using member tf.contrib.integrate.odeint in deprecated module tf.contrib. tf.contrib.integrate.odeint cannot be converted automatically. tf.contrib will not be distributed with TensorFlow 2.0, please consider an alternative in non-contrib TensorFlow, a community-maintained repository, or fork the required code. 162:10: INFO: Added keywords to args of function 'tf.transpose' 173:11: INFO: Added keywords to args of function 'tf.reduce_mean' ```
