pyimport("pyvista") problem

Description

I encounter a problem that when calling PyVista through PyCall by using PyCall; pv = pyimport("pyvista"), whereas there is no problem when directly use pyvista in python. I do use the same conda env for both python and Julia (/lustre/home/.julia/adcme/bin/python). I have tested setting ENV["PYTHON"] or Conda.add way or
pip install pyvista==0.30.0rc1 or conda install -c conda-forge pyvista or conda install -c conda-forge xvfbwrapper, then rebuilding PyCall and restarting Julia etc., but the problem remains.

The errors are as below.

The Python package pyvista could not be imported by pyimport. Usually this means
that you did not install pyvista in the Python version being used by PyCall.

PyCall is currently configured to use the Python version at:

/lustre/home/.julia/adcme/bin/python

and you should use whatever mechanism you usually use (apt-get, pip, conda,
etcetera) to install the Python package containing the pyvista module.

One alternative is to re-configure PyCall to use a different Python
version on your system: set ENV["PYTHON"] to the path/name of the python
executable you want to use, run Pkg.build("PyCall"), and re-launch Julia.

Another alternative is to configure PyCall to use a Julia-specific Python
distribution via the Conda.jl package (which installs a private Anaconda
Python distribution), which has the advantage that packages can be installed
and kept up-to-date via Julia.  As explained in the PyCall documentation,
set ENV["PYTHON"]="", run Pkg.build("PyCall"), and re-launch Julia. Then,
To install the pyvista module, you can use `pyimport_conda("pyvista", PKG)`,
where PKG is the Anaconda package that contains the module pyvista,
or alternatively you can use the Conda package directly (via
`using Conda` followed by `Conda.add` etcetera).

I use Julia through singularity exec julia_latest.sif julia. I am working on an HPC cluster without sudo privilege.

Thanks.

PyCall/src/PyCall.jl:550 に示されている pyimport エントリポイントから開始し、報告された Python 環境で using PyCall; pyimport("pyvista") を再現してください。報告された libX11.so.6 ImportError と Singularity/HPC の構成を調査してください。対応している構成、またはインポートを成功させる具体的な PyCall の変更を特定できれば完了です。
