python imageio.get_reader() returns 格式错误

Question

import imageio

reader = imageio.get_reader("./t.mp4")

如上图，用python3.6.10，returns:

>>> reader = imageio.get_reader("../")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/tristan_jia/workspace/py3.6/venv/lib/python3.6/site-packages/imageio/core/functions.py", line 129, in get_reader
    return format.get_reader(request)
  File "/home/tristan_jia/workspace/py3.6/venv/lib/python3.6/site-packages/imageio/core/format.py", line 168, in get_reader

    raise child_exception_type(errno_num, err_msg, err_filename)
OSError: [Errno 8] Exec format error: '/home/tristan_jia/.imageio/ffmpeg/ffmpeg-linux64-v3.3.1'

我到处搜索，但没有看到任何类似的问题。脚本运行在Opensuse Leap 15.1，和我用的系统有关系吗？

我更新了 imageio（从 2.3.0 到 2.9.0）包以及 ffmpeg-python 包，现在运行良好。
