Looks like our version of kdb (3.1) was too old to have scov, svar, so just deleted those imports from the init.py file.

[sashkab]

I don't think we test with 3.1, as this version is somewhat old. But thanks for your report and the workaround. We will try to add support in future version.

internal issue 1054.

[sashkab]

This has been resolved internally. Expected fix will be released in PyQ 5.0.

[perfecto25]

Just adding in case anyone hits this issue running KDB 3.1

all you need to do is adjust this line for version import,

vi /home/user/py3/lib64/python3.6/site-packages/pyq/__init__.py

#line 624
# change kver to 3.2

    if kver < 3.2:
        for new in ['scov', 'svar', 'sdev']:
            names.remove(new)
