rk3399pro板子跑示例代码mobilenetv1失败

刷了3.0的固件，运行rknn-toolkit中的例子mobilenetv1失败，打印信息如下，在板子上直接运行的，需要设置什么吗？

W The target_platform is not set in config, using default target platform rk1808.
W The channel_mean_value is deprecated. Please use mean_values and std_values to replace it.
W:tensorflow:From /home/toybrick/.local/lib/python3.7/site-packages/tensorflow_core/python/framework/func_graph.py:915: py_func (from tensorflow.python.ops.script_ops) is deprecated and will be removed in a future version.
Instructions for updating:
tf.py_func is deprecated in TF V2. Instead, there are two
    options available in V2.
    - tf.py_function takes a python function which manipulates tf eager
    tensors instead of numpy arrays. It's easy to convert a tf eager tensor to
    an ndarray (just call tensor.numpy()) but having access to eager tensors
    means `tf.py_function`s can use accelerators such as GPUs as well as
    being differentiable using a gradient tape.
    - tf.numpy_function maintains the semantics of the deprecated tf.py_func
    (it is not differentiable, and manipulates numpy arrays). It drops the
    stateful argument making all functions stateful.

W:tensorflow:From /home/toybrick/.local/lib/python3.7/site-packages/tensorflow_core/python/ops/resource_variable_ops.py:1630: calling BaseResourceVariable.__init__ (from tensorflow.python.ops.resource_variable_ops) with constraint is deprecated and will be removed in a future version.
Instructions for updating:
If using Keras pass *_constraint arguments to layers.

需要设置target和devices吗？我直接在板子上跑的应该不需要设置吧
