问题
I need to use the following imports in a Jupyter notebook on IBM Bluemix
import swiftclient
from keystoneclient import client
If I were on my local workstation, I could use pip to install the libraries, but how do I do it on Bluemix? Another post suggests adding a requirements.txt file and a Procfile file into the root directory of my Python application, but I don't see how to do this with a notebook. Any suggestions?
Here is the code:
#!pip install --upgrade pip
!pip install python-swiftclient
!pip install python-keystoneclient
import swiftclient
from keystoneclient import client
# Object Store credentials (generated by Insert to code)
credentials = {
'auth_url':'****',
'project':'****',
'project_id':'****',
'region':'dallas',
'user_id':'****',
'domain_id':'****',
'domain_name':'****',
'username':'****',
'password':"""****""",
'filename':'Warehousing-data.json',
'container':'notebooks',
'tenantId':'****'
}
# Establish Connection to Bluemix Object Store
connection = swiftclient.Connection(
key=credentials[password],
authurl=credentials[auth_url],
auth_version='3',
os_options={"project_id": credentials[projectId],
"user_id": credentials[userId],
"region_name": credentials[region]})
# The data files should now be accessible through calls of the form
# connection.get_object(credentials[container], fileName)[1]
# See https://developer.ibm.com/recipes/tutorials/using-ibm-object-storage-in-bluemix-with-python/
# and https://github.com/saviosaldanha/IBM_Object_Store_Python_Example/blob/master/storage_recipe_example.py

I don't know why it complains about the pip version. Doesn't Bluemix control that? And when I used !pip install --upgrade pip it complained about that too. I've been trying to make this work for over a month! Very frustrating.
回答1:
You need to use the --user flag, because as user you do not root access to the system.
Try the following code:
!pip install --user python-swiftclient
!pip install --user python-keystoneclient
However, I can see from you error messages that you service instance is quite old. It would be better, if you switch to the new offering "IBM Data Science Experience": http://datascience.ibm.com/
