take notes for studying tensorflow

tensorflow_note.md

Recommand: Cuda 8.0, cudnn 6.0

1. why cannot I use tensorboard?

• before start tensorboard, make sure add following codes:

file_writer = tf.summary.FileWriter('log_path', sess.graph)

• then start tensorboadrd:

tensorboard --logdir log_path

• when you see a promote site, copy it and open in browser.

2. why cannot see the changes in tensorboard(using jupyter)?

• you need use following codes first when run new changes

file_writer = tf.summary.FileWriter('log_path', sess.graph)

3. tensorflow not found in pip

• Maybe you have a 32-bit Python ,you need a 64-bit version of Python. As for now Tensorflow only support Python 3.4, 3.5 64-bit version. refer to: stackoverflow

4. pip install jupyter or start jupyter meet srror

• if you use windows, the reason maybe encoding, you can using following step: c:\program files\python36\lib\site-packages\pip\compat_init_.py:
  return s.decode('utf_8') -> return s.decode('cp936') or
  using other terminal liake Git Bash to install jupyter

5. Annoying log message !

• tf.logging.set_verbosity(tf.logging.ERROR)
