我在AWS EC2上啓動了一個使用ubuntu作爲AMI的實例。使用conda更新軟件包時出錯
然後我運行一個腳本來安裝jupyter筆記本，並能夠通過IP地址和特定端口訪問它。 我寫的代碼是這樣的一個：
sudo apt-get install git
git clone https://gist.github.com/rashmibanthia/5a1e4d7e313d6832f2ff nb
. nb/jupyter_notebook_ec2.sh
cd;mkdir notebook;cd notebook
tmux new -s nb
jupyter notebook --certfile=~/certs/mycert.pem --keyfile ~/certs/mycert.key
現在我在筆記本上。這是我的問題。當我嘗試導入一些包和類時，出現錯誤。例如這條線：
from sklearn.gaussian_process import GaussianProcessRegressor
我得到這個：
ImportError Traceback (most recent call last) in() ----> 1 from sklearn.gaussian_process import GaussianProcessRegressor
ImportError: cannot import name 'GaussianProcessRegressor'
所以我嘗試更新scikit學習包與暢達更新暢達scikit學習，但我有另一個錯誤：
