Get an error importing the _robotsim module when calling import klampt

[wanderin-earth]

Hello! When I try running the Jupyter examples, an error occured and it reminded me that there's no _robotisim module. So I followed your instructions, using the Dependencies program to open _robotisim.pyd and found that WLDAP32.dll and WS2_32.dll had missing imports. What should I do next? Thanks.

These are necessary system files, and it’s unclear why they aren’t working on your system. I suggest downloading them from a reputable site like the following link, and put the extracted DLLs in the folder containing robotsim.pyd.

I downloaded them and put them in the robotsim.pyd folder, but it was not so efficacious. And the error info seemed like this:

---

ImportError: No module named '_robotsim'

During handling of the above exception, another exception occurred:

Thanks!

Still a dependency issue, most likely. Could you show a screenshot of what libraries Dependencies says are missing?

These are the two files.

It appears that these need to be in your windows/system32 folder. Something seems amiss with your windows installation, as these are standard system files.
