Isis3: Conda installation fails on libtiff dependency

[kbowley-asu]

Attempting to install isis3 with the conda installation instructions results in the following:

Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - isis3
  - libtiff==4.0.9=0

It appears that libtiff==4.0.9=0 is not available.

$ conda search libtiff==4.0.9

@kbowley-asu What OS are you on?

[kbowley-asu]

I've had the same result on Ubuntu 16.04, Ubuntu 18.04, and Mac 10.13.5

[kbowley-asu]

This is starting with a fresh install of Miniconda on each platform.

[jlaura]

I wonder if this is due to the environment.yml hard pinning, e.g., environment.yml: libtiff==4.0.9=0 to libtiff>=4.0.9. I wonder if the issue is that the build number is being specified and that build number has been purged from conda-forge.

We also have an open issue (#615) where we have been discussing the hard pinning to dependencies. I think that this is likely what you are encountering.

I will give this a test and a build on my Mac and see if that is the issue. If so, we can get a PR in to update the environment.yml after all of the tests have been executed. Thanks for reporting!

Hey @jlaura, thanks for all the great work you and the team do! Did you have any luck reproducing and testing this?

I experienced the same conda installation failure as @kbowley-asu described above, with conda failing to find isis3 and libtiff==4.0.9=0.

I am using Ubuntu 18.04.1 and Anaconda 5.3 (Python 3).

[seignovert]

Exactly the same issue here on Centos7 and Fedora27.
Changing the environment.yml to libtiff>=4.0.9 should fix it.

Side note: the lastest version of libtiff is now 4.0.10.

@camisatx Last I checked @jlaura was working on this, but he's going to be in and out of the office over the holidays.

I am able to re-produce this error. We're planning to push out 3.6.1 sometime next week. I'm going to check the pr from @seignovert and hopefully it can go out with 3.6.1

[jlaura]

@camisatx @jessemapel I am in and out. I got a build going with this, but was getting errors from the geos library when I unpinned liftiff. I am in next week to have another go at this.

[jessemapel]

For future reference, fixing the ISIS3 build environment files will only fix problems for people making new build environments. We need to update the ISIS3 conda build recipe in a similar fashion and push up a brand new 3.6.0 build. Only then, will the Anaconda runtime requirements for installing ISIS3 be fixed.

[jessemapel]

This has been fixed for the ISIS3 build environment but it's going to take a whole new release. We're planning to fix this for all of our dependencies and then push a new build out. That should happen in a week or two depending on holidays, etc.

Watch for 3.6.1

[jessemapel]

This should now be fixes 🎉

Go ahead and re-try installing now. You'll get version 3.6.1 which is 3.6.0 with a fix for this and a fix for a bug in cubeit.

[jessemapel]

I recommend you clear out your anaconda package cache prior to installing. Run conda clean --all in both your base environment and the environment you are installing ISIS into. This will cause Anaconda to re-download all of the packages, and will make your install take more time based on how fast your connection is (it's about 2 GB of dependencies).

Installed successfully on my Ubuntu 18.04 machine. I appreciate the work and thanks for the early Christmas present! *<:-)

@jessemapel Awesome job! I am going to close. @kbowley-asu please reopen if you still have an issue.
