## Commandline

`jstream` comes with a cli tool for quick viewing of parsed values from JSON input:

```bash
jstream -d 1 < input.json
```

```json
{"colors":["red","green","blue"],"desc":"RGB"}
{"colors":["cyan","magenta","yellow","black"],"desc":"CMYK"}
```

detailed output with `-v` option:
```bash
cat input.json | jstream -v -d -1

depth	start	end	type   | value
2	018	023	string | "RGB"

// Run a function containing a MatMul op and check its output.
// If heavy_load_on_streaming_rpc is true, send some rpc requests before the one
// which creates a remote input, to simulate a scenario that the remote input
// is not ready when we start running an op or a function.

  Args:
    environ_cp: copy of the os.environ.
    var_name: string for name of environment variable, e.g. "TF_NEED_CUDA".
    ask_for_var: string for how to ask for user input.
    var_default: default value string.

  Returns:
