在linux服务器端，安装了TF2.2，训练了一个模型mobilenet模型，保存为h5文件，现在需要将给模型转为tflite移动端，但是出现了一下问题：
tensorflow.lite.python.convert.ConverterError: Could not find toco_from_protos binary, make sure your virtualenv bin directory or pip local bin directory is in your path.
In particular, if you have installed TensorFlow with --user, make sure you add the install directory to your path.
For example:
Linux: export PATH=$PATH:~/.local/bin/
Mac: export PATH=$PATH:~/Library/Python//bin
Alternative, use virtualenv.
模型转换的代码如下所示：
model = load_model(h5path)
converter = tf.lite.TFLiteConverter.from_keras_model(model)
litemodel = converter.convert()
open(litepath,"wb").write(litemodel)
h5path和litepath是两个路径的变量，确定无误。
也试过模型不保存直接再训练后放到from_keras_model里面 但是遇到的问题还是一样
