Hi Saswati and the rest of Autonians,<br>
<br>
Could you please test <br>
<br>
/opt/miniconda3-new<br>
<br>
and<br>
<br>
/opt/miniconda3-py38<br>
<br>
<br>
on LOV3. Note only LOV3 has two new instances of conda.<br>
<br>
miniconda3-new is the fresh installation of Python 3.7.7 which seems to<br>
fixes linking problem for me. <br>
<br>
miniconda3-py38 is python 3.8.3 which we probably should start using in<br>
the near future.<br>
<br>
Considering the pace of Python development and its importance for our<br>
lab I propose to have two miniconda installations per server (last two<br>
consequtive releases)<br>
<br>
/opt/miniconda-py37<br>
<br>
/opt/miniconda-py38<br>
<br>
I know that many people have their own installations of Conda which is<br>
not really optimal. If I get positive feed back I will go ahead and<br>
refresh miniconda installations on all nodes running RedHat 7.8.<br>
<br>
Cheers,<br>
Predrag<br>
