# How To Run 'nnpackage' (for beginners)
## 0. Environment
This document is based on an experience with ...
```
- Architecture : armhf
- OS : ubuntu 18.04
```
## 1. What is 'nnpackage'?
'nnpackage' is the input of nnfw and the output of nncc.
'nnpackage' contains all data (such as model, MANIFEST, custom_op) that requires to run a given model.
'nnpackage' is a Zip archive in the following structure:
```
nnpackage
├── custom_op
├── metadata
│ └── MANIFEST
└── mymodel.model
```
For more information, find the document [nnpackage/spec/10_packaging_and_manifest.md](../../../nnpackage/spec/10_packaging_and_manifest.md)
## 2. How to generate nnpackage?
'nnpackage' can be generated from either '.circle' or '.tflite'.
In this example, we generate 'nnpackage' from '.tflite'.
[1] Find 'model2nnpkg.sh'.
```
nnfw/tools/nnpackage_tool/model2nnpkg/model2nnpkg.sh
```
[2] Get any \*.tflite model file.
You can simply use a file in test framework directory, 'nnfw/tests/framework/cache/'.
If you don't have /cache directory, download them with command
```
cd nnfw
MODELFILE_SERVER={MODELFILE_SERVER_LINK} ./tests/framework/run_test.sh --download=on
For {MODELFILE_SERVER_LINK}, put appropriate server link.
```
In this example, we will use 'nnfw/tests/framework/cache/add/1D/add_test1.tflite'
[3] Simply run.
```
$./model2nnpkg.sh add_test1
```
Now, you got add_test1 directory. Check into the directory to find the hierchical structure inside.
## 3. How to set up an environment and run?
[1] Build 'nnfw'.
After build, you can see an execution file 'nnfw/Product/armv7l-linux.debug/out/bin/nnpackage_run'.
For how to build, check out the document [docs/nnfw/howto/CrossBuildForArm.md](../../../docs/nnfw/howto/CrossBuildForArm.md).
[2] Install package 'libhdf5-cpp-100'.
```
$ sudo apt install libhdf5-cpp-100
```
[3] Run nnpackage.
```
$ ./nnpackage_run add_test1
```
Note that you need to put an whole 'add_test_1' directory,
because 'nnpackage' means an archive, not a single file.
