Please remove this directory

C:\Users\Pranjal\AppData\Roaming\Python

Also, please do not use pip to install packages that can be installed by conda in the future. This error was caused because you installed Numpy with pip.

@steff456, please take a look at this one. The idea is very simple: please change the ImportError below by an Exception to catch any kind of error when importing Numpy at that point:

spyder/spyder/plugins/variableexplorer/widgets/objectexplorer/attribute_model.py

Lines 28 to 33 in 3433a2d

	try:
	import numpy as np
	except ImportError:
	_NUMPY_INSTALLED = False
	else:
	_NUMPY_INSTALLED = True
