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

http://yt-project.org/docs/2.6/examining/generic_array_data.html?highlight=load_uniform_grid

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

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

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/d9502d84802972ba3e644d2d5c47b87f73a6bd08/doc/get_yt.sh

This script installs yt using the miniconda python distribution, which includes a precompiled python and openSSL library.

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.

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-versions-and-going-back
.

But it wont update to 3.0 and still shows as 2.6.1

Kindly help

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:

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...
