jcrist opened a new issue, #826:
URL: https://github.com/apache/datafusion-python/issues/826
In `datafusion 40.1.0` a bug was added where a `SessionContext` cannot be
created when specifying only a `SessionConfig`. This is due to a small
copy-paste error in the `SessionContext.__init__`.
```python
In [1]: import datafusion
In [2]: config = datafusion.SessionConfig()
In [3]: ctx = datafusion.SessionContext(config)
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
Cell In[3], line 1
----> 1 ctx = datafusion.SessionContext(config)
File
~/miniforge3/envs/ibis/lib/python3.11/site-packages/datafusion/context.py:448,
in SessionContext.__init__(self, config, runtime)
427 """Main interface for executing queries with DataFusion.
428
429 Maintains the state of the connection between a user and an instance
(...)
445 df = ctx.read_csv("data.csv")
446 """
447 config = config.config_internal if config is not None else None
--> 448 runtime = runtime.config_internal if config is not None else None
450 self.ctx = SessionContextInternal(config, runtime)
AttributeError: 'NoneType' object has no attribute 'config_internal'
```
