Why can't python suddenly not run functions from imported modules?

Question

I have some weird problems with python, and I don't know how to fix it.

For the following code: df = pd.DataFrame.from_dict(mydict)

I get the error: AttributeError: module 'pandas' has no attribute 'DataFrame'

The same happens with other modules. Another example: L = np.sqrt((x2-x1)**2 + (y2-y1)**2)

Gives the error: AttributeError: module 'numpy' has no attribute 'sqrt'

I suspect that I might have managed to mess up my paths?

When I try to print my sys.path, this is what happens:

import sys

sys.path
Traceback (most recent call last):

  File ~\AppData\Local\anaconda3\lib\site-packages\traitlets\traitlets.py:653 in get
    value = obj._trait_values[self.name]

KeyError: 'type_printers'


During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File ~\AppData\Local\anaconda3\lib\site-packages\IPython\core\formatters.py:706 in __call__
    type_pprinters=self.type_printers,

  File ~\AppData\Local\anaconda3\lib\site-packages\traitlets\traitlets.py:700 in __get__
    return self.get(obj, cls)

  File ~\AppData\Local\anaconda3\lib\site-packages\traitlets\traitlets.py:656 in get
    default = obj.trait_defaults(self.name)

  File ~\AppData\Local\anaconda3\lib\site-packages\traitlets\traitlets.py:1868 in trait_defaults
    return self._get_trait_default_generator(names[0])(self)

    d[numpy.float64] = lambda obj, p, cycle: p.text(self.float_format % obj)

AttributeError: module 'numpy' has no attribute 'float64'

Is there any way to fix this?

Answer 1

The error message suggests that the DataFrame class is not being found within the pandas module. Make sure that you have installed the pandas library correctly. You can use the following command to install or upgrade pandas:

pip install --upgrade pandas

Also Make sure there are no other files named pandas.py or variables named pandas in the same directory as your script. This can cause conflicts and prevent the correct pandas module from being imported.
