運行《tensorflow實戰(zhàn)google深度學(xué)習(xí)框架》這本書中關(guān)于多線程操作的例子時，
import tensorflow as tf
import numpy as np
import threading
import time
def MyLoop(coord, worker_id):
while not coord.should_stop():
if np.random.rand()<0.1:
print "Stoping from id: %d\n" % worker_id,
coord.request_stop()
else:
print "Working on id: %d\n" % worker_id,
time.sleep(1)
coord = tf.train.Coordinator()
threads = [threading.Thread(target=MyLoop, args=(coord, i, )) for i in xrange(5)]
for t in threads:t.start()
coord.join(threads)
出現(xiàn)了如下錯誤：
Traceback (most recent call last):

以為是書中代碼寫錯了，仔細檢查了一下，代碼沒什么問題斯撮，于是我就把代碼精簡泽铛，刪的就剩下兩行了：
import tensorflow as tf
coord = tf.train.Coordinator()
還是上面的錯誤
記得以前也用過tf.train，可是也沒見過這中錯誤啊贱勃。于是乎昂勒，我找來以前的代碼冬殃，把代碼刪的也是就剩兩行，運行叁怪，沒錯誤。于是我就很納悶了深滚，仔細對比了這兩個文件奕谭，發(fā)現(xiàn)惟一的不同就是文件名，我想會不會是文件名導(dǎo)致出錯呢痴荐，原來的文件名是threading.py血柳，我把它改為test.py，運行生兆，成功难捌。又把文件名改為thread.py，運行鸦难，同樣的錯誤根吁。看來文件名真的會影響程序的運行昂媳巍击敌！
為什么會出現(xiàn)這樣的錯誤呢？我猜想是不是跟計算機系統(tǒng)中的文件重名了呢拴事？搜索了一下沃斤，果不其然，/usr/lib/python3.5/concurrent/futures 中有thread.py這個文件刃宵，/usr/lib/python2.7 中有threading.py這個文件衡瓶。為了驗證我的猜想，我把多線程操作的這個文件名改成跟/usr/lib/python2.7目錄下任意一個文件名相同牲证，于是又出現(xiàn)了上面的錯誤哮针，同時也驗證了我的猜想。以上。
