Using the latest miniconda2 I created a conda environment & then did all my conda package installs. Then when I finished I realized I had FORGOT TO ACTIVATE the environment (I'm dizzy) with the command
source activate myenv
so all my conda installs went into the local/system wide environment. I simply did
conda uninstall package-name
for all the packages but I'm certain not all the dependencies were removed. For example, conda install of matplotlib showed
The following NEW packages will be INSTALLED:
cycler: 0.10.0-py36_0
dbus: 1.10.20-0
expat: 2.1.0-0
fontconfig: 2.12.1-3
freetype: 2.5.5-2
glib: 2.50.2-1
gst-plugins-base: 1.8.0-0
gstreamer: 1.8.0-0
icu: 54.1-0
jpeg: 9b-0
libffi: 3.2.1-1
libgcc: 5.2.0-0
libiconv: 1.14-0
libpng: 1.6.30-1
libxcb: 1.12-1
libxml2: 2.9.4-0
matplotlib: 2.0.2-np113py36_0
pcre: 8.39-1
pyparsing: 2.2.0-py36_0
pyqt: 5.6.0-py36_2
qt: 5.6.2-5
sip: 4.18-py36_0
which conda shows
/home/cargo/miniconda2/bin/conda
First I created the environment
conda create -n myenv python=3
Then I did all the conda installs
conda install numpy
conda install pandas
.
.
conda install statsmodels
Then I realized I failed to activate the environment b/c the terminal prompt was
cargo@cargo-VirtualBox:~$ INSTEAD OF (myenv)cargo@cargo-VirtualBox:~$
The terminal prompt is what got my attention before I even tried to do anything else; I'm 110% certain I didn't activate the environment as I can't find the command in the bash history. Next I did uninstalls for all the conda packages as stated above. I guess it's good now that I no longer see the python3 packages in the local/root environment but I can't explain/understand why?
