使用 ck 框架安装 TensorFlow Lite 失败

Question

我在http://cknowledge.org/shared-programs.html#image-classification-tflite 找到了一个使用 TensorFlow Lite 对图像进行分类的程序。我正在关注提供的自述文件，但在为 android23 安装 lib-tflite-1.7.0-src-static 包时卡住了 - ck 框架没有找到我的 android ndk：

plam@mrk-23:~$ ck install package:lib-tflite-1.7.0-src-static --target_os=android23-arm64

****** Installation notes: ******
You can download and install Native Android NDK for your platform from

You can also download CrystaX NDK (extra libs and improved C++ support) from

       Would you like to open wiki pages about related software (with possible installation info) (y/N):

CK error: [package] no registered CK environment was found for "C++ compiler" dependency with tags="compiler,lang-cpp" and setup={"target_os_bits": "64", "host_os_uoa": "linux-64", "target_os_uoa": "android23-arm64"}!

我认为是因为android ndk安装在我们集群上一个不常见的地方：/misc/android-ndk-r17b

有谁知道如何告诉这个 ck 框架在不标准的地方检测我的 android ndk？我使用 Ubuntu 18.04 并从 https://github.com/ctuning/ck 的 GitHub 安装 ck。

非常感谢！

您必须首先帮助 CK 在非正常路径中从 Android NDK 中检测您的 GCC，如下所示：

$ ck detect soft:compiler.gcc.android.ndk --target_os=android23-arm64 --search_dirs=<<INSTALLATION PATH OF ANDROID NDK>>

然后您可以检查 CK 是否将您的 Android NDK 注册为虚拟环境，如下所示：

$ ck show env --target_os=android23-arm64
$ ck virtual env --tags=android,ndk,gcc --target_os=android23-arm64

您现在应该可以按如下方式重新启动 TensorFlow 的安装：

$ ck install package:lib-tflite-1.7.0-src-static --target_os=android23-arm64
$ ck compile program:image-classification-tflite --target_os=android23-arm64 --speed
$ ck run program:image-classification-tflite --target_os=android23-arm64

您还可以通过以下类似方式从 Android NDK 中检测 Clang：

$ ck detect soft:compiler.llvm.android.ndk --target_os=android23-arm64 --search_dirs=<<INSTALLATION PATH OF ANDROID NDK>>

但我不确定它是否适用于上述 tflite 包 - 你可以尝试...

如果您需要，可以在这里找到其他可以被CK检测到的软件：http://cKnowledge.org/shared-soft-detection-plugins.html

顺便说一句，我建议在 CK 邮件列表或 Slack 频道中提出此类问题 - 你可能会更快地获得帮助：https://github.com/ctuning/ck/wiki/Contacts
