Utilizing this system greatly simplifies the installation burden, environment activation, sequestration and general day to day use of the VMTK tool. With the VMTK 1.4 release, we have transitioned to utilizing Anaconda Python as our primary method for packaging and distribution. Linux and MacOSX machines support python 2.7, 3.5+ In the next release of VMTK, python 2.7 support will be dropped entirely for all platforms. VMTK 1.4+ requires python 3.5+ on Windows 10. We no longer support python 2.7 on Windows builds. The general dependencies of VMTK 1.4+ are automatically installed by the anaconda package manager. The vmtk distribution is released under a BSD-like license.To see a detailed list of changes for each version of vmtk please refer to the changelog.New vmtk users might want to read the Getting Started guide.Binary packages are supported by Orobix Srl.Pip install Installing from Python SourceĪlternatively if all you can find is Python source code, you can still perform the install to your activated Python VE. To install via pip you perform this command in your activated Python VE: Pip pulls applications from the Python package index ( ). Some popular channels for scientific computing resources are: conda-forge and bioconda. You can also add conda repositories so that it will autofetch from more places by adding a channel to it via this command: Both conda and pip have depdency checks, so performing and install in your VE will autofetch whatever dependencies the application needs and install them for you. When you activate a VE, you can install programs without any administrator intervention. The good thing about virtual environments you create in your workspace is that you have ownership permissions over them. Where 'myvm' is the name of the VM you want to delete and then select 'y' at the prompt to confirm. If you want to delete your VM, enter the following command: See the conda and pip sections further down on the page for more details. You have complete ownership over the virtual environment, which means you can install applications whenever you'd like. The prompt indicates that your VM is active so the path to Python is now the one from your VE. You are still logged in to your regular session on Arc, and everything works as normal (submitting jobs, opening files, etc). This will change the prompt to let you know which Vm you're ~]$ conda activate myvm To select or "activate" a vm, enter the following command: Myvm/work/abc123/.conda/envs/myvm Activating a VM The asterisk indicates which one is ~]$ conda env list You can create multiple vms to suit your needs. Select 'y' and let it install to the default location. You load them like any other module on shamu.Īfter you load your preffered Anaconda module you can create a new python vm with the name 'myvm' by running the command: Two versions of the anaconda distribution of python are loaded on Arc The Anaconda module runs python 2.7, and Anaconda3 runs Python 3.6. By making Vms you can ensure an application can create a stable environment to run. Some programs may need specific versions of modules to work correctly and may cause incompatibilies with the current system library. If you need to install your own programs/modules in python you can do it via creating vms.
