如何修复 Jupyter notebook 依赖项？ ModuleNotFoundError：没有名为“boto3”的模块

Question

I am running EMR cluster(AWS) but I do not understand how notebook imports packages. I am running PySpark kernel.

import boto3
No module named 'boto3'
Traceback (most recent call last):
ModuleNotFoundError: No module named 'boto3'

print (sys.version) shows

3.7.6 (default, Feb 26 2020, 20:54:15) 
[GCC 7.3.1 20180712 (Red Hat 7.3.1-6)]

print(sys.executable) shows

/tmp/1594625399736-0/bin/python

I have both Conda and pip3 install of boto3.

How to solve this?

Answer 1

Are you using pyspark? If yes, then you need to install the packages in the spark context. Refer to this AWS document: https://aws.amazon.com/blogs/big-data/install-python-libraries-on-a-running-cluster-with-emr-notebooks/

similarly install any dependency packages if you see module not found error on import. Make sure the versions are compatible.
