尝试运行TransitFlow / Processing，但出现错误

如何解决尝试运行TransitFlow / Processing，但出现错误

点击此链接后，我刚刚安装了TransitFlow和预处理：

https://github.com/transitland/transitland-processing-animation

然后运行以下代码：

python transitflow.py --name=chicago --bBox=-87.992249,41.605175,-87.302856,42.126747 --clip_to_bBox --exclude=o-9-amtrak,o-9-amtrakcharteredvehicle

一切正常，除了最后，我得到了这个错误：

success!
5 operators successfully downloaded.
0 operators Failed.
Concatenating individual operator outputs.
Calculating trip segment bearings.
Traceback (most recent call last):
  File "C:\Users\Evan\Anaconda3\lib\site-packages\pandas\core\indexes\base.py",line 2891,in get_loc

  File "pandas\_libs\hashtable_class_helper.pxi",line 1683,in pandas._libs.hashtable.PyObjectHashTable.get_item

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Evan\Anaconda3\lib\site-packages\pandas\core\generic.py",line 3571,in _set_item
    loc = self._info_axis.get_loc(key)

    raise KeyError(key) from err
KeyError: 'bearing'

During handling of the above exception,another exception occurred:

我查看了transportflow.py，并检索了导致我遇到此错误的代码行（我认为）：

 df['bearing'] = df.apply(lambda row: calc_bearing_between_points(row['start_lat'],axis=1)

有什么想法吗？

谢谢
