anaconda - how can I install a library with conda without affecting other libraries in Python -


i give following example illustrate question.

i plan install libpng 16 on ubuntu machine following command: conda install libpng. however, update following packages:

    cairo:        1.12.18-3         --> 1.12.18-6              fontconfig:   2.11.1-3          --> 2.11.1-6               freetype:     2.5.2-1           --> 2.5.5-2                libgfortran:  1.0-0             --> 3.0.0-1                libpng:       1.5.13-1          --> 1.6.27-0               numpy:        1.8.2-py27_1      --> 1.11.3-py27_0          opencv:       2.4.9-np18py27_0  --> 3.1.0-np111py27_1      pixman:       0.26.2-0          --> 0.32.6-0               scikit-image: 0.9.3-np18py27_0  --> 0.13.0-np111py27_0     scipy:        0.14.0-np18py27_0 --> 0.19.0-np111py27_0

i not want update these libraries reasons. may possible libpng updated alone?

if want this, there --no-update-dependencies flag conda install command:

conda install --no-update-dependencies libpng

beware things might break though. more here: https://conda.io/docs/commands/conda-install.html

a similar flag available conda update flag well, in case you're updating package, not installing new.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
