Tensorflow：ios編譯錯誤（重複符號）

Question

我正在爲ios編譯tensorflow，並按照https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/makefile1的說明操作。

我能順利通過前兩個步驟：

sh tensorflow/contrib/makefile/download_dependencies.sh 



sh tensorflow/contrib/makefile/compile_ios_protobuf.sh 

但是，我得到了重複的符號錯誤？當我跑

make -f tensorflow/contrib/makefile/Makefile \ 
TARGET=IOS \ 
IOS_ARCH=ARM64 

任何人都可以幫忙嗎？感謝

下面是錯誤：

Answer 1

有可能有多個，

libtensorflow-core.a in your project. 

所以嘗試刪除它，不是再次做到這一點。

您的項目中有一些重複的文件或方法或變量。所以請嘗試搜索並刪除它們。

在撰寫本文時，TensorFlow的HEAD不適合iOS。它會幫助，如果這樣的瞬態問題被關閉，所以這裏有兩個通用機制（如果我錯過了一個相關的問題鏈接，請幫助！）：

• 如果要檢查出任何種類的最前沿（如果使用Git，通常是HEAD的master），期望中斷。發佈標籤往往更加穩定，應該建立良好，缺乏最新變化的代價。例如，git tag列出標籤，通常有vX.Y.Z模式可供選擇。
• 如果您必須從源代碼重新構建，通常會更好 - 並非總是需要 - 先清理當前構建。清潔需要時間，所以您可以樂觀並直接構建，如果出現任何問題，則清理/構建。通常，命令看起來像make -f tensorflow/contrib/makefile/Makefile clean。

此外，TensorFlow的正式構建系統依賴於巴澤爾和make構建系統是大多數時間滯後：依靠make所有平臺有更高的風險在HEAD（再次打破，這並非總是如此）。請注意0​​構建系統位於tensorflow/contrib目錄中，該目錄明確擱置。
