Can't "import gradio as gr" but I've installed gradio

[LuZixuan2022]

I've installed it as in the readme. I created the audioldmenvironment as prompted and installed gardioin it, but when I execute "(audioldm) D:audioldm2>python app.py", I get the following error. Traceback (most recent call last): File "app.py", line 5, in <module> import gradio as gr File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\gradio\__init__.py", line 3, in <module> import gradio._simple_templates File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\gradio\_simple_templates\__init__.py", line 1, in <module> from .simpledropdown import SimpleDropdown File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\gradio\_simple_templates\simpledropdown.py", line 6, in <module> from gradio.components.base import FormComponent File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\gradio\components\__init__.py", line 3, in <module> from gradio.components.bar_plot import BarPlot File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\gradio\components\bar_plot.py", line 7, in <module> import altair as alt File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\altair\__init__.py", line 620, in <module> from .vegalite import * File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\altair\vegalite\__init__.py", line 2, in <module> from .v5 import * File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\altair\vegalite\v5\__init__.py", line 2, in <module> from .schema import * File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\altair\vegalite\v5\schema\__init__.py", line 3, in <module> from .core import * File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\altair\vegalite\v5\schema\core.py", line 7, in <module> from altair.utils.schemapi import SchemaBase, Undefined, UndefinedType, _subclasses File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\altair\utils\__init__.py", line 1, in <module> from .core import ( File "C:\ProgramData\anaconda3\envs\audioldm\lib\site-packages\altair\utils\core.py", line 27, in <module> import pandas as pd File "C:\Users\Road\AppData\Roaming\Python\Python38\site-packages\pandas\__init__.py", line 22, in <module> from pandas.compat import is_numpy_dev as _is_numpy_dev # pyright: ignore # noqa:F401 File "C:\Users\Road\AppData\Roaming\Python\Python38\site-packages\pandas\compat\__init__.py", line 25, in <module> from pandas.compat.numpy import ( File "C:\Users\Road\AppData\Roaming\Python\Python38\site-packages\pandas\compat\numpy\__init__.py", line 4, in <module> from pandas.util.version import Version ModuleNotFoundError: No module named 'pandas.util'

Then I ran "(audioldm) D:audioldm2>audioldm2 -t "Musical constellations twinkling in the night sky, forming a cosmic melody."" , and then the following error appeared.
