Hi,
I am stuck with solving an ModuleNotFoundError when using a submodule
panel.pane.Markdown.
My impression from the docs is, that this could be solved with hooks and /
or hidden imports, but so far the error is still there.
Any hints or code snippets on how to solve this problem would be very
welcome, thanks in advance.
I am using a current miniconda python on a windows machine.
Here is my code, unfortunaletely this minimal running example has still
auite some lines of code.:
A) The application file, named "paneltest.py"
*import panel as pn*
*if __name__ == '__main__':*
* print('Panel Test with Markdown')*
* # version a)*
* # To see version a) in a webpage comment out version b)*
* test = pn.widgets.TextInput(name='A widget', value='A string')*
* # version b)*
* # to see version a) comment out this line*
* test = pn.pane.Markdown('#Test') *
* # opens a page in your browser showing *
* # a) an widget*
* # or b) throws a ModuleNotFoundError*
* server = test.show(threaded=False)*
B) the specs-file, named "paneltest.spec"
*# run at console in the directory e.g. with the following options #
pyinstaller -D -y paneltest.spec from PyInstaller.utils.hooks import
collect_submodulesblock_cipher = None# Change path to python version on
your workstationpypath = 'C:\\[your path]\\miniconda3\\'# This does not
solve the ModuleNotFoundErrorhiddenimports_markdown =
collect_submodules('markdown')# 'markdown.extensions.extra' is among the
collected submodulesprint(hiddenimports_markdown)a = Analysis(
['paneltest.py'], pathex=[ 'C:\\Users\\[your path]'],
datas=[ # some html and js files are needed, for simplicity all
files are copied # for these modules, this approach worked solving
issues ( pypath +
'Lib\\site-packages\\pyviz_comms', 'pyviz_comms'),
( pypath + 'Lib\\site-packages\\bokeh',
'bokeh'), ( pypath + 'Lib\\site-packages\\panel',
'panel'), # For this module copying all file does not
solve the ModuleNotFoundError ( pypath +
'Lib\\site-packages\\markdown', 'markdown'), ],
