TypeError: sequence item 1: expected str instance, numpy.float64 found

[jurajjasik]

The error arises from here after upgrading NumPy. The problem is in _convert_input function:

keithley2600/keithley2600/keithley_driver.py

Line 766 in d03691c

value, np.complex

Since NumPy>1.20.0, the use of numpy.complex is deprecated (ref). Instead, complex must be used.
