無法在 macOS 上使用 gdb 調試 tensorflow

Question

我正在嘗試在 macOS Sierra 上使用 GDB 調試 TensorFlow。 我按照帖子上的說明進行操作。在我安裝了用於調試的 tensorflow 開發人員版本后，我嘗試使用 gdb 附加一個 python 會話。

當我運行gdb -p <pid> ：

(gdb)

當我設置斷點時：

(gdb) break TF_NewSession
Function "TF_NewSession" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (TF_NewSession) pending.

然后即使我像帖子所說的那樣運行sess = tf.Session() 。 GDB 永遠不會進入斷點。

Answer 1

好吧，在我更改為在 macOS 上使用lldb后，一切正常。 所以我想這個問題的解決方案是“使用 LLDB 代替 GDB”。
