Safegraph_py unable to run in my local system--juypter lab

[chukwumichaelmary]

I have tried to install the safegraph_py package as provided in the readme documentation 'pip install -q --upgrade git+https://github.com/SafeGraphInc/safegraph_py'; I created a new environment on juypter lab and installed pandas, numpy, and matplotlib. But, however, when I copy and run the script sgpy.test_me(), sgpy.help(), I get an AttributeError like:
AttributeError Traceback (most recent call last)
Cell In[5], line 3
1 # test the library
----> 3 sgpy.test_me()

AttributeError: module 'safegraph_py_functions.safegraph_py_functions' has no attribute 'test_me'

Could you help by any chance. Thanks.
