┌ Warning: Error requiring ScikitLearn from MLJModels:
│ LoadError: PyError (PyImport_ImportModule
│ 
│ The Python package sklearn could not be found by pyimport. Usually this means
│ that you did not install sklearn in the Python version being used by PyCall.
│ 
│ PyCall is currently configured to use the Python version at:
│ 
│ /usr/bin/python3
│ 
│ and you should use whatever mechanism you usually use (apt-get, pip, conda,
│ etcetera) to install the Python package containing the sklearn 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 sklearn module, you can use `pyimport_conda("sklearn", PKG)`,
│ where PKG is the Anaconda package the contains the module sklearn,
│ or alternatively you can use the Conda package directly (via
│ `using Conda` followed by `Conda.add` etcetera).

┌ Warning: Error requiring ScikitLearn from MLJModels:
│ LoadError: PyError (PyImport_ImportModule
│ 
│ The Python package sklearn could not be found by pyimport. Usually this means
│ that you did not install sklearn in the Python version being used by PyCall.
│ 
│ PyCall is currently configured to use the Python version at:
│ 
│ /usr/bin/python3
│ 
│ and you should use whatever mechanism you usually use (apt-get, pip, conda,
│ etcetera) to install the Python package containing the sklearn 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 sklearn module, you can use `pyimport_conda("sklearn", PKG)`,
│ where PKG is the Anaconda package the contains the module sklearn,
│ or alternatively you can use the Conda package directly (via
│ `using Conda` followed by `Conda.add` etcetera).

┌ Warning: Error requiring ScikitLearn from MLJModels:
│ LoadError: PyError (PyImport_ImportModule
│ 
│ The Python package sklearn could not be found by pyimport. Usually this means
│ that you did not install sklearn in the Python version being used by PyCall.
│ 
│ PyCall is currently configured to use the Python version at:
│ 
│ /usr/bin/python3
│ 
│ and you should use whatever mechanism you usually use (apt-get, pip, conda,
│ etcetera) to install the Python package containing the sklearn 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 sklearn module, you can use `pyimport_conda("sklearn", PKG)`,
│ where PKG is the Anaconda package the contains the module sklearn,
│ or alternatively you can use the Conda package directly (via
│ `using Conda` followed by `Conda.add` etcetera).
