Error in importing shapefile in jupyter using geopanda

I am using Jupyter from Anaconda and trying to import a shapefile with following command line:
import geopandas as gpd
gdf = gpd.read_file('C:\Downloads\Temp\shapefile\regions.shp')
print (gdf)
gdf.plot()
However, I got following errors:

"TypeError: <class 'numpy.typing._dtype_like._SupportsDType'> is not a generic class" when importing the plotly.express library

I want to create a simple plotly chart from a .csv file that I fetched from an API.
I import the library, pass the dataframe, and get the error:
TypeError: <class 'numpy.typing._dtype_like._SupportsDType'> is not a generic class
code:
import plotly.express as px
df=pd.read_csv('file.csv')
What might be the problem, and what does this error mean?

I got the same error, it is dependency issue, plotly.express (5.9.0) is not working with numpy==1.20, if you upgrade numpy==1.21.6 it will solve your error.
pip install numpy==1.21.6

I was having same issue when I updated xarray. I tried updating numpy but conda environment was restricting it. Updating the whole conda environment helped me resolve this error.
conda update --all

NumpyBackend' object has no attribute 'tucker'

I have some codes for doing image compression using svd and some more codes for experiments.
So I have the following code for experiment:
plt.figure(figsize=(20,12))
for i,rank in enumerate([2,10,20]):
plt.subplot(2,3,i+1)
plt.imshow(svd_compression(image1,rank))
plt.title("rank:%i - compression: %.2f%%" %(rank,svd_compress_ratio(image1,rank)*100))
for i,rank in enumerate([2,10,20]):
plt.subplot(2,3,i+4)
plt.imshow(svd_compression(image2,rank))
plt.title("rank:%i - compression: %.2f%%" %(rank,svd_compress_ratio(image2,rank)*100))
plt.show()
But I got the following errors:

Theano step gives File in wrong format error

what am i missing?
thanks

Whatever the issue was creating a python 3.4 environment together with
conda install mingw libpython
solved it.

What solved my issue is installing Python 2.7 version of anaconda

I got the same error using ipython. Using just python I imported theano without problem. Subsequent uses with ipython worked fine after the first compilation with just python.
