Python asammdf 库需要依赖项
Python asammdf library requires dependencies
我是 Python 的新手，尝试 运行 名为 'asammdf' 的库的示例代码 'Working with MDF'（代码可在此处找到：https://asammdf.readthedocs.io/en/master/examples.html)
当我 运行 .py 脚本时，我收到以下错误消息：
WARNING:root:Signal plotting requires pyqtgraph or matplotlib
Traceback (most recent call last):
File "/Users/martin/PycharmProjects/mdfp3/WorkingWithMDF.py", line 46, in
mdf4_cut.get('Float64_Signal').plot()
我在 PyCharm 中使用依赖管理器添加了 pyqtgraph 和 matplotlib 包，但没有成功。
我做错了什么？

运行 包的 pip install 命令导致 'Requirement already satisfied' 语句（见下文）
(venv) martins-mbp-2:mdfp3 martin$ pip install pyqtgraph
Requirement already satisfied: pyqtgraph in ./venv/lib/python3.7/site-packages (0.10.0)
Requirement already satisfied: numpy in ./venv/lib/python3.7/site-packages (from pyqtgraph) (1.17.4)

事实证明，您需要 PyQt5 以及 pyqtgraph 或 matplotlib。 GUI 包被认为是 'optional'，这可以解释为什么它们不会自动安装。仅供参考，我通过阅读 asammdf\gui\plot.py 文件中的异常发现了这一点。
可以使用此 pip 命令安装 GUI 依赖项
pip install asammdf[gui]
