client hangs #26
Description
Activity
I'm running v12.3 with Python 3.6.9 on Ubuntu.
The following works:
session.evaluate(wlexpr('Range[5]'))But I can definitely reproduce a hang with:
session.evaluate(wl.WolframAlpha("number of moons of Saturn", "Result"))Notably the following does return an answer, so there might be a separate issue with the second argument of WolframAlpha:

In[2]:= WolframAlpha["2+2", "Result"] /usr/local/Wolfram/WolframEngine/12.3/SystemFiles/FrontEnd/Binaries/Linux-x86-64/WolframPlayer: error while loading shared libraries: libasound.so.2: cannot open shared object file: No such file or directorySolved with:
sudo apt-get install libasound2I assume that libasound2 should be made an explicit dependency, or an instruction listed.
Here is the list of dependencies that the FrontEnd requires. Any FrontEnd dependent function eventually need them:
linux-vdso.so.1 libGL.so.1 libpthread.so.0 librt.so.1 libdl.so.2 libX11.so.6 libfontconfig.so.1 libstdc++.so.6 libm.so.6 libc.so.6 /lib64/ld-linux-x86-64.so.2 libgcc_s.so.1 libuuid.so.1 libz.so.1 libGLX.so.0 libGLdispatch.so.0 libasound.so.2 libxcb.so.1 libexpat.so.1 libXext.so.6 libXau.so.6 libXdmcp.so.6 libbsd.so.0The command to get these:
In [1]: from wolframclient.evaluation import WolframLanguageSession
In [2]: from wolframclient.language import wl, wlexpr
In [3]: session = WolframLanguageSession('/opt/WolframEngine/12.1/Executables/WolframKernel')
In [4]: session.evaluate(wl.WolframAlpha("number of moons of Saturn", "Result"))
<<< hangs here indefinitely
In [5]: session.evaluate(wlexpr('Range[5]'))
<<< hangs here indefinitely
Steps:
Ubuntu 18.04.5 LTS
conda version : 4.8.4
