```python
def is_dask_collection(x)
    try:
        return x.__dask_graph__() is not None
    except (AttributeError, TypeError):
        return False
```
to
```python
def is_dask_collection(x):
    return hasattr(x, ""__dask_graph__"") and callable(x.__dask_graph__) and inspect.isclass(x)
```

This means that it never actually calls `__dask_graph__`, which is not ideal because `xarray` objects return `None` if the wrapped array is not a dask collection.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1228474784
