Pipeline fails with import error for dataiku

I'm trying to run the below example on my jenkins node:

https://community.dataiku.com/t5/Knowledge-Base/Building-a-Jenkins-pipeline-for-Dataiku-DSS/ta-p/10201
In one of the stages, I created python venv which install the requirments.txt file. I can see in the console log that dataiku-api-client was installed with version 8.0.0, but still, it fails later with the first command of import dataiku:

ModuleNotFoundError: No module named 'dataiku'
My python version is 3.7.4
any idea what's wrong with that?

首先，使用 Python 3.7.4、已创建的虚拟环境和 requirements.txt，复现链接的 Dataiku 示例中的 Jenkins pipeline。检查安装了 dataiku-api-client 8.0.0 的环境与运行 import dataiku 的环境；当导入在 pipeline 中正常工作或原因已记录时，即视为完成。
