Hi Erica,

To add to what Britton said, if you use the install script at yt-project.org, all the necessary packages yt depends on will be installed in a separate directory for yt's use only. They will not interfere with your FLASH install or anything else, and can be deleted without affecting the rest of your system. For this reason, it's the preferred install method for yt for all OS types.

Hi Erica,

Welcome to yt!

I don't know much about the macports installation method.  Hopefully, the person who set that up can respond.

In the mean time, I recommend you try using the install script.  I have a mac and have used it successfully a number of times.  If you go to yt-project.org and click on "GET YT", just follow the instructions there.

Hi all,

I tried using macports to install yt and ran into a couple of issues.

First, there was a conflict because I had hdf5 installed to use flash and yt required hdf5-18. Secondly, after uninstalling hdf5 to see what would happen, I received these errors:

Error: Checksum (md5) mismatch for yt-2.2.tar.gz Error: Checksum (sha1) mismatch for yt-2.2.tar.gz Error: Checksum (rmd160) mismatch for yt-2.2.tar.gz Error: Target org.macports.checksum returned: Unable to verify file checksums Error: Status 1 encountered during processing.

Any ideas?

Thanks!

Erica

Hi Tom,

Thanks for your help!

Will this also resolve the hdf5 problem? I tried running flash with hdf5-18 but got a ton of errors.

Hi Erica,

I think the checksum mismatch was due to the fact that I was using tar files from bitbucket rather than the official tar files on pypi, and the bitbucket tar file must be dynamically generated. I've updated the port description to include yt-2.3 from pypi, and have also included a patch to ensure that iyt runs with ipython 0.12+ (see http://hg.yt-project.org/yt/issue/375/iyt-is-hard-coded-to-only-work-with).

The port database is updated every hour, so in a couple of hours, try:

sudo port selfupdate

then:

port search py27-yt

if you see:

py27-yt @2.3 (python, science) Astrophysical simulation Analysis and Viz'

(i.e. with 2.3, not 2.2), then you can install it:

sudo port install py27-yt

(Note, iyt is available as iyt-2.7)

Let me know if things do still not work in a couple of hours!

Cheers, Tom
