<div>After the upgrade to Ubuntu 18.04, my VM blow up and I had to re-build it from scratch. I'm not saying that I've made it exactly like the one that used the previous version, so I might miss some dependencies. I do not use/contribute to Biopython on my
local Wndows machine anymore (because some module gave problem when I was developing some tests).</div>
<div><br>
</div>
<div><b>Ben:</b></div>
<div>I've followed your suggestion. Directly on terminal (not via PyCharm or other IDE) I've entered the virtual environment dedicated to biopython and build+installed it from the source code. I get this in the console:</div>

If I run the python console from the source directory I'm not able to run the tests mentioned in the installation guidelines, but numpy is fine (linking to

<div>Francesco, in which directory are you running Python?</div>
<div>I can replicate this error only if I try these commands in the biopython source directory. In that case, python imports from the current directory, not from the installed directory.</div>
<div>Importing Bio.Cluster will also fail for the same reason.</div>
<div>Numpy has the same problem; there they show an informative error message if somebody tries to import numpy from the source tree:</div>
