Hi,

I'm having a hard time installing hic2cool. Pip fails:

pip install -e hic2cool/ 
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

I need it for HiCAssembler which ueses python 2.7. Any conflict here?

Thanks F

carlvitzthum commented 5 years ago

Hi @francicco

Thanks for raising the issue! The problem was caused by a new release of pandas 4 days ago (0.25.0rc0) that deprecates Python 2. I have pinned the previous pandas version to fix the problem. Please use hic2cool==0.7.3 to get this change -- it's in the master branch, if you are using an editable install.

One more note: hic2cool will be ending support for Python 2.7 upon its official end of life. See here for more info.

Best, Carl

Hi @carlvitzthum,

Thanks for the reply. I have to use Python2 because HiCAssembler needs it. So, this is what I'm doing:

virtualenv HiCAssembler
source HiCAssembler/bin/activate
pip install git+https://github.com/4dn-dcic/hic2cool.git

But I get the error anyway

You are using pip version 9.0.1, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

If I install it with Python3 I get these errors when I install HiCAssembler

ERROR: hicmatrix 7 has requirement cooler==0.8.2, but you'll have cooler 0.8.5 which is incompatible.
ERROR: hicexplorer 2.2.1.1 has requirement cooler==0.8.2, but you'll have cooler 0.8.5 which is incompatible.

If I remove cooler==0.8.5 and install cooler==0.8.2 then hic2cool complains:

ERROR: hic2cool 0.7.3 has requirement cooler>=0.8.5, but you'll have cooler 0.8.2 which is incompatible.

What to do? F

Hi @francicco

Both of the following work for me in clean Python 2.7 virtual environments:

pip install hic2cool==0.7.3
pip install git+https://github.com/4dn-dcic/hic2cool.git

As such, it installs correctly in an isolated and the problem is not from the hic2cool side. I took a quick look at the HiCAssembler requirements file and the way they have set up their package, it will automatically attempt to use the newest versions of packages when installing. This may be the cause of the original issue; it was what I fixed in hic2cool version 0.7.3 (my comment above).

I quickly looked into your problem and here's some feedback that may be helpful:

I will not downgrade the cooler version for hic2cool, since it requires features in 0.8.5. I hope this is helpful.

Best, Carl

It's a mess. I manually installed (via pip install -e .) all dependencies using python 2.7 with the exception of matplotlib. HiCExplorer now complains because it wants matplotlib==3.0.*, but matplotlib now wants Python3.
