How to fix Jupyter Notebook pandas error (OSError: [WinError 193] %1 is not a valid Win32 application)

I am currently working on the Yelp regression project in a Machine Learning course.

The project requires me to open a Jupyter notebook and import pandas as py.

I use the Anaconda navigator to open Jupyter notebook. I get the following:

(OSError: [WinError 193] %1 is not a valid Win32 application)

when I try to import pandas for my code. The full message:

OSError Traceback (most recent call last)
<ipython-input-2-ed70324e10b6> in <module>

----> 1 import pandas as pd
2 

3 
businesses = pd.read_json('yelp_business.json', lines = True)

4 reviews = pd.read_json('yelp_review.json', lines = True)

5 users = pd.read_json('yelp_user.json', lines = True)


~\AppData\Roaming\Python\Python37\site-packages\pandas\__init__.py in <module>

9 for dependency in hard_dependencies:

10 try:

---> 11 __import__(dependency)

12 except ImportError as e:

13 missing_dependencies.append("{0}: {1}".format(dependency, str(e)))


~\AppData\Roaming\Python\Python37\site-packages\numpy\__init__.py in <module>

139 # Allow distributors to run custom init code

--> 140 from . import _distributor_init

141 

142 from . import core


~\AppData\Roaming\Python\Python37\site-packages\numpy\_distributor_init.py in <module>

24 # NOTE: would it change behavior to load ALL

25 # DLLs at this path vs. the name restriction?

---> 26 WinDLL(os.path.abspath(filename))

27 DLL_filenames.append(filename)

28 if len(DLL_filenames) > 1:


~\Anaconda3\lib\ctypes\__init__.py in __init__(self, name, mode, handle, use_errno, use_last_error)

354 

355 if handle is None:

--> 356 self._handle = _dlopen(self._name, mode)

357 else:

358 self._handle = handle


OSError: [WinError 193] %1 is not a valid Win32 application

I've already tried uninstalling and installing python, anaconda, and pandas.

lt is likely that your environment is messed up. As you can see from the traceback, there are two python environments involved here:

C:\Users\nouma\AppData\Roaming\Python\Python37

C:\Users\nouma\Anaconda3

Please make sure your PATH is clean and you can actually remove one of them first.

You probably downloaded the 64-bit pandas on a 32-bit system. Uninstall and reinstall but pay extra attention to this.
