The TestApp is being used for different purposes as described below
To quickly test our framework in Cocoapods, simply run
pod install
This will pull the latest version of LibTorch
from Cocoapods. To run the app, you need to have your model copied to the project as well as a config.json
file, which can be found in the benchmark folder.
The TestApp is currently being used as a dummy app by Circle CI for nightly jobs. The challenge comes when testing the arm64 build as we don't have a way to code-sign our TestApp. This is where Fastlane came to rescue. Fastlane is a trendy automation tool for building and managing iOS applications. It also works seamlessly with Circle CI. We are going to leverage the import_certificate
action, which can install developer certificates on CI machines. See Fastfile
for more details.
For simulator build, we run unit tests as the last step of our CI workflow. Those unit tests can also be run manually via the fastlane scan
command.
The benchmark folder contains two scripts that help you setup the benchmark project. The setup.rb
does the heavy-lifting jobs of setting up the XCode project, whereas the trace_model.py
is a Python script that you can tweak to generate your model for benchmarking. Simply follow the steps below to setup the project
- In the PyTorch root directory, run
IOS_ARCH=arm64 ./scripts/build_ios.sh
to generate the custom build from Master branch - Navigate to the
benchmark
folder, runpython trace_model.py
to generate your model. - In the same directory, open
config.json
. Those are the input parameters you can tweak. - Again, in the same directory, run
ruby setup.rb
to setup the XCode project. - Open the
TestApp.xcodeproj
, you're ready to go.
The benchmark code is written in C++, you can use UI_LOG
to visualize the log. See benchmark.mm
for more details.
For those who want to do perf testing but don't want to touch XCode, bootstrap.sh
is the right tool for you. It'll automatically build and install the app on your device. That being said, it does require you to have
- A valid iOS dev certificate installed on your local machine.
- A valid provisioning profile for code signing
- A valid team identifier
To run the script, simply type the command below and make sure your phone is connected via USB.
./bootstrap
Open the app on your device, the benchmark result will be displayed on the screen.
Note This requires ios-deploy to be installed. Please have a look at ios-deploy. To quickly install it, use
npm -g i ios-deploy
