Protobuf Error for JupySQL in IPython
Loading the JupySQL extension in IPython fails:  
```python
In [1]: %load_ext sql
```  
```console
ImportError: cannot import name 'builder' from 'google.protobuf.internal' (unknown location)
```  
The solution is to fix the `protobuf` package. This may require uninstalling conflicting packages, e.g.:  
```python
%pip uninstall tensorflow
%pip install protobuf
```
