<p class="MsoNormal">There have been a number of posts about this issue, it seems to be that conda installs an older version of netcdf (4.62.) with this bug, instead of the latest version (4.6.3). You could fix it by somehow installing the latest version of
netcdf4 into your conda environment, or installing NCL from binary like back in the good old days.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">An alternative hack – which I in no way advocate or endorse, nor would I ever admit to using myself – is to invoke NCL in the following fashion:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">ncl 2>dev/null …<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">You’ll still get NCL error/warning messages<o:p></o:p></p>
