Might be useful... Using python 2.7.12 and ReportLab 3.5.31, "from reportlab.graphics.barcode import qr" causes errors, I think it's because rl_exec imports later.
The following hidden_imports got it to work: hiddenimports=[ 'reportlab.graphics.barcode.common', 'reportlab.graphics.barcode.code128', 'reportlab.graphics.barcode.code93', 'reportlab.graphics.barcode.code39', 'reportlab.graphics.barcode.code93', 'reportlab.graphics.barcode.usps', 'reportlab.graphics.barcode.usps4s', 'reportlab.graphics.barcode.ecc200datamatrix', ], -- You received this message because you are subscribed to the Google Groups "PyInstaller" group.
