vk error on RHEL7

[beechwood13]

Hi, Installation VCF-kit using pip went smoothly and it looked that I had all dependencies installed. However, if I start any of the vk commands, I get the following error:

File "/usr/bin/vk", line 7, in from vcfkit.vk import main File "/usr/lib/python3.4/site-packages/vcfkit/vk.py", line 24, in from utils import lev, message ImportError: cannot import name 'lev'

utils==0.9.0 is installed

Thanks for your help in advance !

Facing the same issue in RHEL 7.

Same issue here

Same issue. Any news?

Currently, vcf-kit only works with Python 2.7

How do you change what version of python you're running vcf-kit through?

[danielecook]

@mayasheth Check out pyenv and pyenv-virtualenv. You can use them to set up python on a per-directory basis.

I just ran into this issue on CentOS 7 as well. I tried with the system's Python 2.7.5, Python 3.4.9, and a custom Python 2.7.13 virtual environment.

In both Python 2 environments vk fails with:

$ vk
Traceback (most recent call last):
  File "/tmp/vcfkit/bin/vk", line 6, in <module>
    from vcfkit.vk import main
  File "/tmp/vcfkit/lib/python2.7/site-packages/vcfkit/vk.py", line 27, in <module>

    raise ValueError("threshold must be numeric and non-NAN, try "
ValueError: threshold must be numeric and non-NAN, try sys.maxsize for untruncated representation

On Python 3.4 it fails with:

$ vk
Traceback (most recent call last):
  File "/tmp/vcfkit-python3/bin/vk", line 11, in <module>
    load_entry_point('VCF-kit==0.1.6', 'console_scripts', 'vk')()

  File "/tmp/vcfkit-python3/lib64/python3.4/site-packages/vcfkit/vk.py", line 24, in <module>
    from utils import lev, message
ImportError: No module named 'utils'

What is the correct Python to run VCF-Kit with? Can you please add some notice to the README.md to guide us? Thanks!

I'm in the exact same situation as @alanorth. Any suggestions how to get it running?

[danielecook]

@alanorth @chromatimera It isn't compatible with Python3 currently.

I'm think there must be some sort of incompatibility with an update to numpy. I'm a bit stretched on time right now, but I would like to find a solution in the near future.

A quick workaround would be to use conda or docker.

Please see: https://bioconda.github.io/recipes/vcfkit/README.html

Which also lists an available docker container:

docker pull quay.io/repository/biocontainers/vcfkit

Hi @danielecook ! I was using VCF-kit over the last few days and after a conda update it is now giving an error as below:

I would really appreciate some help!

If anyone is still trying to make VCF-kit work. It works on python 2.7.10 and gcc/4.7.2
