 RedisAI currently supports PyTorch (libtorch), Tensorflow (libtensorflow), TensorFlow Lite, and ONNXRuntime as backends. This section shows the version map between RedisAI and supported backends. This extremely important since the serialization mechanism of one version might not match with another. For making sure your model will work with a given RedisAI version, check with the backend documentation about incompatible features between the version of your backend and the version RedisAI is built with.

 ## Loading the Module
 To load the module upon starting the Redis server, simply use the `--loadmodule` command line switch, the `loadmodule` configuration directive or the [Redis `MODULE LOAD` command](https://redis.io/commands/module-load) with the path to module's library.

 Models, like any other Redis and RedisAI data structures, are identified by keys. A Model's key is created using the [`AI.MODELSTORE` command](commands.md#aimodelstore) and requires the graph payload serialized as protobuf for input.
 
-In our examples, we'll use one of the graphs that RedisAI uses in its tests, namely 'graph.pb', which can be downloaded from [here](https://github.com/RedisAI/RedisAI/raw/master/tests/flow/test_data/graph.pb).

 ??? info "Downloading 'graph.pb'"
     Use a web browser or the command line to download 'graph.pb':
 
     ```
-    wget https://github.com/RedisAI/RedisAI/raw/master/tests/flow/test_data/graph.pb
+    wget http://dev.cto.redis.s3.amazonaws.com/RedisAI/test_data/graph.pb
     ```
 
 You can view the computation graph using [Netron](https://lutzroeder.github.io/netron/), which supports all frameworks supported by RedisAI.
