# OperatorType kMerge error during tflite convert

I've got a model based on mobilenet. I want to convert it to tensorflow tflite, but I'm getting the following error

```

```

What's the problem? I've checked couple of times, my training phase is desabled and I'm using inference environment. Sometimes I get **Mul** in stead of **BatchNormalization**.
