Issues when building NNtrainer for Android
KirillP2323 opened this issue · comments
Hello, I am setting up Android development for NNtrainer, I'm following instructions here: https://github.com/nnstreamer/nntrainer/blob/main/docs/how-to-run-example-android.md
I'm stuck on the build step. When I run ./tools/package_android.sh, the installation process is being stuck for about 20 minutes after lines Message: preparing blas, Message: preparing ml api and Message: preparing tflite, because either tflite backbone or interpreter is enabled. After a couple of hours, the build throws the following error:
$ ./tools/package_android.sh
...
Message: preparing tflite, because either tflite backbone or interpreter is enabled

ninja: build stopped: subcommand failed.
The long wait issue might be because of a proxy on my machine: connection eventually times out, and tensorflow-2.3.0 does not end up in builddir.
The usual meson build finishes successfully. I also tested the build on another machine without proxy issues, and it also finished successfully.
cibot: Thank you for posting issue I found that the installation process uses wget, the issue was solved by adding ~/.wgetrc file with proxy.
