问题
In a Python 3.5 notebook, backed by an Apache Spark service, I had installed BigDL 0.2 using pip. When removing that installation and trying to install version 0.3 of BigDL, I get this error: (linebreaks added for readability)
AssertionError: Multiple .dist-info directories:
/gpfs/fs01/user/scbc-4dbab79416a6ec-4cf890276e2b/.local/lib/python3.5/site-packages/BigDL-0.3.0.dist-info,
/gpfs/fs01/user/scbc-4dbab79416a6ec-4cf890276e2b/.local/lib/python3.5/site-packages/BigDL-0.2.0.dist-info
However, neither of these directories exists:
!ls -al /gpfs/fs01/user/scbc-4dbab79416a6ec-4cf890276e2b/.local/lib/python3.5/site-packages/

drwx------ 3 scbc-4dbab79416a6ec-4cf890276e2b users 4096 Nov 8 06:12 ..
What's wrong? How can I install the new version of the package after removing the old one?
回答1:
The directory paths in the error message are wrong. The Python 3.5 kernel on DSX specifies a build directory for pip by setting the environment variable PIP_BUILD. The multiple dist-info directories are there:
!printenv PIP_BUILD ; ls -l $PIP_BUILD/*
/tmp/scbc-4dbab79416a6ec-4cf890276e2b/pip-build

drwx------ 8 scbc-4dbab79416a6ec-4cf890276e2b users 117 Nov 7 02:02 bigdl
drwx------ 2 scbc-4dbab79416a6ec-4cf890276e2b users 135 Nov 7 02:02 BigDL-0.2.0.dist-info
drwx------ 2 scbc-4dbab79416a6ec-4cf890276e2b users 135 Nov 8 06:12 BigDL-0.3.0.dist-info
To fix the problem, remove the build directory:
!rm -rf $PIP_BUILD
After that, pip can install the package without problems:
!pip install --no-dependencies bigdl==0.3
Collecting bigdl==0.3
