I installed Anaconda 3 2.3.0 on Windows xp. It is supposed to be the last version of anaconda to support windows xp as it contains python 3.4.3, and python 3.4.x is the last version of python to support windows xp.
When installing a package with
conda install
,one of its dependencies was updating conda to conda 4.x. conda 4.x crashed in the commandline when running conda install . This made anaconda unusable that i uninstalled anaconda.
My question, is it possible to lock versions of packages ? For the two use cases:
If only one of the 2 use cases is possible or is known or is easier, please write it as answer.
There are two bits to this. First, you can prevent conda from auto-updating by changing the configuration option auto_update_conda to False:
conda config --set auto_update_conda False
The other bit is to pin packages to certain versions. For those packages you don't want to update, you can pin the version by adding a line to a file called pinned (you might need to create it) in the environment's conda-meta directory. The syntax is
[The code] below [placed in
conda-meta/pinned] forces NumPy to stay on the 1.7 series, which is any version that starts with 1.7, and forces SciPy to stay at exactly version 0.14.2:numpy 1.7.* scipy ==0.14.2
See the documentation for more information.
Pin for conda install (=): package=1.0
vs.
Pin for pip install (==): package==1.0
Try
pip install <package name==version no*>
for instance
pip install musdb==0.2.*
That would pin your package
