Re: [yt-users] problem with yt update to 3.0

Dear yt:
I am currently running yt version 2.6.1 and want to update to version 3 (to read text files). Could you provide me link to so?
I tried it using yt update --all as per the link
http://yt-project.org/doc/yt3differences.html#updating-to-yt-3-0-from-old-ve... .
But it wont update to 3.0 and still shows as 2.6.1
Kindly help
Thanks in advance

Hi Nathan:
Thanks for your reply.
I had done that before installing version 2.X. I used to get errors as below. Even now I keep getting the same error after reinstalling from scratch. The error comes after "installing pip". I tried it on my pc and also on cluster but same issues.

This is happening because python is unable to link against an openSSL library.
Can you try using the get_yt.sh script install of the install_script.sh script:
https://bitbucket.org/yt_analysis/yt/raw/d9502d84802972ba3e644d2d5c47b87f73a...
This script installs yt using the miniconda python distribution, which includes a precompiled python and openSSL library.

I had done that before installing version 2.X. I used to get errors as below. Even now I keep getting the same error after reinstalling from scratch. The error comes after "installing pip". I tried it on my pc and also on cluster but same issues.

I get the same error over here. I think it's unrelated to the other error. The relevant portion of the C stack trace is here:

Unfortunately, I have no idea how to debug this from here...

Dear Nathan:
I will try it and let you know. In the meanwhile, could you let me know if yt supports loading text file for version 2.6.1? If so could you point me to examples for the same.
Thanks in advance

I get the same error over here. I think it's unrelated to the other error. The relevant portion of the C stack trace is here:

Unfortunately, I have no idea how to debug this from here...

Dear Nathan:
Thank you for your help

Dear Nathan:
As per your advice I am trying to load my text file to numpy array. But there are two ways to so using numpy.loadtxt and numpy.fromfile. Could you suggest which of them is more efficient for large files and more suitable for yt (if any)?
Thanks in advance

Dear Nathan:
I am trying to load my data from a file by formatting it as numpy array (using np.genfromtxt).
But when I try to load a uniform grid using pf = load_uniform_grid(data, vector.shape, cm_per_mpc, bbox=bbox, nprocs=64).
I get the following error AttributeError: 'module' object has no attribute 'load_uniform_grid'.
Can you suggest the source of the error?
Thank you in advance

If you can format your data as numpy arrays, there are examples of how to load your data into yt here:

yt (2.6.1 or newer) does not support i/o from arbitrary text files.

I get the same error over here. I think it's unrelated to the other error. The relevant portion of the C stack trace is here:

Line 19749 of selection_routines.c corresponds to line 1158 in selection_routines.pyx, which is the place where the fill_mask member variable of the SliceSelector extension type gets defined.
Unfortunately, I have no idea how to debug this from here...

Oh, interesting. Is there a way to circumvent auto-detection of fields?
