由於「找不到符號：_PyBytes_AsString」而無法運行tensorboard

Question

我一直在嘗試運行tensoarboard沒有任何成功。我可以看到函數tf.summary.FileWriter（）正在工作，因爲我可以看到logFile是在正確的文件夾中創建的。但是，當我在終端運行：

tensorboard --logdir=/private/tmp/mnist/2 --port=6006 

我得到：

我不知道該如何應對找不到符號：平面命名空間：_PyBytes_AsString和預期。有這link談論我認爲類似的錯誤，但它並沒有幫助我。

我使用的代碼可以在此tutorial被發現，我在MacOS塞拉利昂10.12.1

Answer 1

我有同樣的問題跟你的一樣。就我而言，我在OS X 10.11.6上通過Homebrew安裝了python，python3包，並且我在python3上執行了我的項目。
在我看來，「Symbol not found」問題的症狀可能是由於我們的tensorboard鏈接到錯誤的python框架造成的。
我發現這個問題在Homebrew/legacy-homeb'python3 framework installation incomplete? #20591'處打開。
像samueljohn說，「框架沒有正確鏈接到自制的前綴。」
所以，我只是跟着他的指導下，創造了我自己的鏈接。

brew update 
brew unlink python python3 
brew link python 
brew link python3 

請原諒我有限的英語能力，但希望這可以幫助。
