Hi,
Using the absolutely latest 64-bit Python versions of the originpro (0.0.7) and OriginExt (1.1.1) packages available on pypi.org, both of these calls succeeded for me:
ret = op.open(r'\\files\Dropbox\Tech\test.opju')
ret = op.open(r'//files\Dropbox\Tech\test.opju')
While this one failed:
ret = op.open('//files/Dropbox/Tech/test.opju')
Using our latest internal build of 2021 (and 2020b actually).
I suspect your issue has something to do with crossing OS file systems.
BTW, CP is correct- You'll need to use Origin 2021 when it is released because you will run into compatibility issues with our Python packages and 2020b if you do anything meaningful with the packages. Plus, we won't support the packages with any Origin version prior to 2021.
Thanks,
