AttributeError: 'ParquetFile' object has no attribute 'row_groups'

Pythonistas!
Not sure what I am doing wrong while reading a parquet file here.
I have all the necessary packages installed - pandas, fastparquet & pyarrow
The code literally is reading the parquet file
import pandas as pd
FILE = 'file://minute_equities_all/minute/A/AA.parquet'
pd = pd.read_parquet(FILE,engine='fastparquet')
This keeps giving me,
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/ppatel/opt/miniconda3/envs/quant/lib/python3.10/site-packages/pandas/io/parquet.py", line 493, in read_parquet

rgs = filter_row_groups(self, filters) if filters else self.row_groups
AttributeError: 'ParquetFile' object has no attribute 'row_groups'
Changing the engine to pyarrow also doesn't help -

Am I missing something here? Any help will be appreciated!

I am suffering similar issue with you. It can be possible to have file path issue. In my case, when i tried to access S3 file, happened that error. and this is permission issue to access S3.

Minimal example opencv, pyinstaller, conda

I'm trying to get a minimal example working using pyinstaller and opencv inside a conda environment.
So far, what I'm doing is:
conda create -n minimal_example python=3 pyinstaller opencv
which leaves me with the following packages:

I have a script called minimal_build.py with the following content:
print('Importing numpy')
import numpy as np
print(np.__version__)
print(np.__file__)
print('Importing OpenCV')
import cv2
I'm trying to package that script into an executable running
pyinstaller minimal_build.py
When running the resulting exe, I get the following output:
Importing numpy

Please install mkl-service package, see http://github.com/IntelPython/mkl-service
exec(bytecode, module.__dict__)

So I'm guessing, that it tries to import numpy from my user folder instead of the package. What am I doing wrong?

I happened to have the same problem as you
Here is the solution I tried:
conda create -n minimal_example python=3.7 pyinstaller
conda activate minimal_example
pip install opencv-python
not conda install opencv
my conda list:

Issue importing scikit-learn: module 'scipy' has no attribute '_lib'

I'm new to Python and am using Anaconda on Windows 10 to learn how to implement machine learning. Running this code on Spyder:
import sklearn as skl
Originally got me this:
Traceback (most recent call last):

ImportError: DLL load failed: The specified module could not be found.
I then went to the command line and did
pip uninstall scipy
pip install scipy
pip uninstall scikit-learn
pip install scikit-learn
and got no errors when doing so, with scipy 1.3.1 (along with numpy 1.17.0) and scikit-learn 0.21.3 being installed according to the command line.
However, now when I try to import sklearn I get a different error:

with the version of scipy not matching up with the version that pip installed. Not sure how significant it is but it seemed strange to me.

Doing pip list returns

pip list says scipy is version 1.3.1, while conda list says it's version 1.3.0. Again, not sure how relevant it is, but seems strange
EDIT 3: I got this error after putting the following lines (suggested by #Brennan) in my command prompt then running the file
pip uninstall scikit-learn
pip uninstall scipy
conda uninstall scikit-learn
conda uninstall scipy
conda update --all
conda install scipy
conda install scikit-learn
This is the new error I get when trying to import sklearn:

ImportError: DLL load failed: The specified module could not be found.
A possible cause of this might be me deleting the mkl_rt.dll file from my Anaconda/Library/bin after encountering the error described here: https://github.com/ContinuumIO/anaconda-issues/issues/10182
This puts me in a predicament, because reinstalling Anaconda to repair this will get me the same "ordinal 242 could not be located" error that I faced earlier, but not repairing it will continue the issue with sklearn...
FINAL EDIT: Solved by installing old version of Anaconda. Will mark as solved when I am able to (2 days)

I ended up fixing this by uninstalling my current version of Anaconda and installing a version from a few months ago. I didn't get the "ordinal 242" error nor the issues with scikit-learn.

I encountered the same error after letting my PC sit for 4 days unattended. Restarting the kernel solved it.
This probably won't work for everyone, but it might save someone a little agony.

I have answerd this here, to my understanding this error is caused by the missing/misplacement of libcrypto file in anaconda3/DLLs folder:
From anaconda3\Library\bin copy below files and paste them in anaconda3/DLLs:
- libcrypto-1_1-x64.dll
- libssl-1_1-x64.dll

This can be fixed by manually adding in the PATH variables in PyCharm to the console.
Open your Anaconda cmd
Activate your Conda environment
Get the full PATH value by typing echo %PATH%
if you are on Windows 7/can't copy the output, cd the cmd to your desktop and type echo %PATH% > path_val.txt
this will create a txt file so you can copy/paste the values easier.
In PyCharm, go to Settings -> Build, Execution, Deployment -> Console -> Python Console -> click the folder on the right of Environment variables.
Click the plus button to add a new Environment Variable
The name should be PATH
The value is the entire output from the echo %PATH% command above.
Click OK, then apply.

You can try to set system environment variables, like "C:\Python\Anaconda3;C:\Python\Anaconda3\Scripts;
C:\Python\Anaconda3\Library\bin;".
Only "C:\Python\Anaconda3\Scripts;" is not enough, and it works to me.

I had the same issue on Windows 10 Pro x64 and PyCharm CE 2018.3
A solution that worked for me: Re-install Anaconda3 for all users (with Admin priveledges) and choose "add python.exe to Path" (even though it is nor recommended). Then PyCharm connected successfully without this error.
A work around that also worked: Use another environment (pyenv or conda). It worked for me when I faced the same issue on
Some other suggestions I saw on Internet:
run Anaconda3\Scripts>conda update --all
but this threw the HTTP connection error rises, which might be related.

if running under a virtual env (i.e. your have issued the command: conda activate <env_name>)
The files (libcrypto-1_1-x64.dll and libssl-1_1-x64.dll) to copy are found under:
C:\USER<username>.conda\envs<env_name>\Library\bin
They have to be copied into:
C:\USER<username>.conda\envs<env_name>\DLLs

None of the above worked for me, but instead it was a problem with OpenSSL on Windows 10 Enterprise. I fixed it by downloading and installing OpenSSL from here: https://slproweb.com/products/Win32OpenSSL.html

Thanks for the answer!
This works definately.
I have answerd this here, to my understanding this error is caused by the missing/misplacement of libcrypto file in anaconda3/DLLs folder:
From anaconda3\Library\bin copy below files and paste them in anaconda3/DLLs:
libcrypto-1_1-x64.dll
libssl-1_1-x64.dll

In my case the error was a result of spinning pipenv from non-base conda env. Setting variable in PyCharm or moving files in base anaconda structure didn't help, because PyCharm looked for these DLLs in my conda env in the middle.
So I had to move files from base conda structure:
C:\Users<username>\AppData\Local\Continuum\anaconda3\Library\bin
To my conda env from which I spinned the final Pipenv I use in PyCharm:
C:\Users<username>\AppData\Local\Continuum\anaconda3\envs<conda_env_name>\DLLs
The files I had to move to have IPython work correctly:
libcrypto-1_1-x64.dll
libssl-1_1-x64.dll
sqlite3.dll
sqlite3.exe
The reason is that not all libraries/binaries are propagated to the virtual envs. Virtual envs are able to find these files in "root Python". Venvs stay lighter thanks to not copying them.
However, PyCharm gets confused in a setup such as mine, and treats the conda env in the middle as a "root Python", and can't find the libraries/bins. This problem can potentially make itself apparent with other dlls or bins.
It may be worth to move all missing files this way.

another solution: edit python3.7's site.py(in Lib dir):
from os.path import join, abspath, dirname
base_path = dirname(dirname(abspath(__file__)))
os.environ['PATH'] = '%s%s' % (
os.environ['PATH'],
join(base_path, 'Library', 'bin'),
)

I had the same issue and my main IDE is Sublime Text 4.
Environment: Windows 10 with Anaconda
What I needed: from cryptography.fernet import Fernet
The marked solution was unachievable for me and the following answer solved it right away:
pip install --upgrade pip
pip uninstall pyopenssl cryptography
pip install pyopenssl cryptography
Validate with:
python -v -c "from OpenSSL import SSL"

Incase someone is searching for Eclipse PyDev, It's same as Rob's answer.
No. 4 can be found at Window -> Preferences -> PyDev -> Interpreters -> Python Interpreters -> Environment -> Click New and add PATH

I have updated to Python 3.8 (with miniconda) and it did not work with Pycharm generating "anaconda-environment-import-ssl-dll-load-fail-error". I have tried several proposals here and tweaked env variables in different way w/o much success.
Finally I have updated to Pycharm 2020.2.3 and it worked like a charm, no tweaks ..

Jupyter-notebook exploding after command conda install -c conda-forge

I hope this post brings you well. I have environment issues that I would love to get assistance on.
I installed geopandas with command:
conda install -c conda-forge geopandas
Then typed jupyter-notebook and got a nasty error, here is what it reads:
