xgboost on Sagemaker notebook import fails

问题

I am trying to use XGBoost on Sagemaker notebook.

I am using conda_python3 kernel, and the following packages are installed:

• py-xgboost-mutex
• libxgboost
• py-xgboost
• py-xgboost-gpu

But once I am trying to import xgboost it fails on import:

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-5-5943d1bfe3f1> in <module>()
----> 1 import xgboost as xgb

ModuleNotFoundError: No module named 'xgboost'

回答1:

In Sagemaker notebooks use the below steps

a) If in Notebook

i) !type python3

ii) Say the above is /home/ec2-user/anaconda3/envs/python3/bin/python3 for you

iii) !/home/ec2-user/anaconda3/envs/python3/bin/python3 -m pip install xgboost

iv) import xgboost

---

b) If using Terminal

i) conda activate conda_python3
ii) pip install xgboost

Disclaimer : sometimes the installation would fail with gcc version ,in that case update pip version before running install

回答2:

try reinstalling

pip uninstall xgboost
pip install xgboost
