Issue 8 LSTM

Issue 7 - tf.nn.nce_loss()


Signature: tf.nn.nce_loss(weights, biases, labels, inputs, num_sampled, num_classes, num_true=1, 
                            sampled_values=None, remove_accidental_hits=False, 
                            partition_strategy='mod', name='nce_loss')

Issue 6 - os.makedir('./data') on Kaggle Kernel

Kaggle kernel supports create a folder path with code os.makedir('./data')
if using a uploaded dataset, it will be saved '../input/'

Refer to notebook tensorflow_skipgram.ipynb

Issue 5 - tf.argmax(vector, 1) same as np.argmax()

tf.argmax(input, axis=None, name=None, dimension=None, output_type=tf.int64)

0：按列计算

1：按行计算

test = np.array([[1, 2, 3], [2, 3, 4], [5, 4, 3], [8, 7, 2]])
np.argmax(test, 0)　　　＃输出：array([3, 3, 1]
np.argmax(test, 1)　　　＃输出：array([2, 2, 0, 0]

tf.argmax(vector, 1)

test[0] = array([1, 2, 3])  #2
test[1] = array([2, 3, 4])  #2
test[2] = array([5, 4, 3])  #0
test[3] = array([8, 7, 2])  #0

tf.argmax(vector, 0)

test[0] = array([1, 2, 3])
test[1] = array([2, 3, 4])
test[2] = array([5, 4, 3])
test[3] = array([8, 7, 2])
# output   :  # [3, 3, 1]

Issue 4 - Open Tensorborad in Kaggle Kernel

open tensorboard locally

writer = tf.summary.FileWriter('./graph1', sess.graph)
writer.close()
sess.close()

!tensorboard --logdir='./graph1'

open tensorboard on Kaggle Kernel

# At first in settings, Make sure that Internet option is set to "Internet Connected"
# After executing this cell, there will come a link below, open that to view your tensor-board

!wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip
!unzip ngrok-stable-linux-amd64.zip
LOG_DIR = './graph1' # Here you have to put your log directory
get_ipython().system_raw(
    'tensorboard --logdir {} --host 0.0.0.0 --port 6006 &'
    .format(LOG_DIR)
)
get_ipython().system_raw('./ngrok http 6006 &')
! curl -s http://localhost:4040/api/tunnels | python3 -c \
    "import sys, json; print(json.load(sys.stdin)['tunnels'][0]['public_url'])"

Issue 2 - Win7 install tensorflow

Re-install to the path without space

$ conda create -n tensorflow pip python=3.5

WARNING: A space was detected in your requested environment path
'e:\Program Files\Anaconda3\envs\tensorflow'
Spaces in paths can sometimes be problematic.
Solving environment: failed

Do as the official guidebook - Installing with Anaconda

$ C:> conda create -n tensorflow pip python=3.5

$ C:> activate tensorflow

$ (tensorflow)C:> pip install --ignore-installed --upgrade tensorflow
