<p>Hi,</p>
<p><br>
</p>
<p>You can look at all the possible fields via `ds.derived_field_list`. Are you sure that ('io', 'sumy') is there? did you try just 'sumy'? FWIW, my 'sumy' field_type is 'flash'.</p>

<p>I guess the presentation migrated to Rochester? <a href="https://flash.rochester.edu/site/flashcode/user_support/yt_flash_informal.pdf" style="font-size: 12pt;">https://flash.rochester.edu/site/flashcode/user_support/yt_flash_informal.pdf</a></p>

<div>Dear all,</div>
<div><br>
</div>
<div>I am a new user of FLASH and trying to sort out how to do the visualization. Visit didn't really work for me since it was giving a plugin error somehow it couldn't recognize the hdf5 file type. So I switched the python tool.
<br>
</div>
<div><br>
</div>
<div>I have done the installations and it seemed successful. However, when I try to plot a sample, I got the following error:<br>
</div>
<div><br>
</div>
<div> raise YTFieldNotFound((ftype, fname), self)</div>
<div>yt.utilities.exceptions.YTFieldNotFound: Could not find field '('io', 'sumy')' in sedov_hdf5_chk_0004</div>
<div><br>
</div>
<div>I couldnt find a solution how to fix this. I would appreciate any help. Besides, I couldn't have an access the presentation in this link
<br>
