When I try to install cairosvg it says requirement satisfied.

But when I try to import it in IDLE, it gives the following error:

This might be because ofcairocffi as it is also giving the following error on import:

OSError: dlopen() failed to load a library: cairo / cairo-2
I have a 64-bit windows based architecture with python 3.5 and have installed cairocffi-0.8.0 which installed without a problem.
I solved this problem using UniConverter2.0.
My environments is
Python 3.7
Windows 10 x64
Install uniconvertor-2.0rc4-win64_headless.msi,
Find the "dll" sub-directory under the UniConverter installation path.(In my case, C:\Program Files\UniConvertor-2.0rc4\dlls)
Add this "dll" path to the system path.
Close VSCode(or other editor) and reopen the project.
Try to run your code again.
Enjoy!

I think is something about directories, but what ??
(base) C:\Users\Henri>pip install tabula-py

I think is installed, just you need to make sure which Python environment yre installing it because maybe is installed in python3 directory, not python2.
I have an issue with the installation of Tensorflow
I just completed installing Tensorflow with
$ pip install --user --upgrade tensorflow
and these are the last lines I get after this installation

and then when I enter the following command:
$ pip install --upgrade tensorflow
I do get a bunch of requirement already up-to-date as per the below .
Requirement already up-to-date: tensorflow in c:\users\xxx\appdata\roaming\python\python36\site-packages

Requirement already up-to-date: protobuf>=3.6.1 in c:\programdata\anaconda3\lib\site-packages (from tensorflow )
Which I interpret as everything is installed and upgraded ( am I wrong here ? )
Now my issue is that when I try to import Tensorflow let say in Jupyter notebook , I get the following error message
ImportError: Traceback (most recent call last):
File "C:\ProgramData\Anaconda3\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 58, in <module>

return _load(spec)
ImportError: DLL load failed: The specified module could not be found.
Failed to load the native TensorFlow runtime.
See https://www.tensorflow.org/install/errors
for some common reasons and solutions. Include the entire stack trace
above this error message when asking for help.
Any idea what could be the reason and what i need to change to get tensorflow up and running ?
Thanks guys in advance for any help with the above issue .
I've solved this problem by downgrading tensorflow to version 2.0 using this command:
pip install tensorflow==2.0
and then use like this :
from tensorflow.keras.applications import vgg19
from tensorflow.keras.models import load_model
I hope it helps.
Can anyone have a look what goes wrong with my pyinstaller?
I also tried to convert a .py file to .exe file, but the same error was generated
Update. 12/15. BTW, I have installed both python 2.7 and python 3 on my computer, would that be the problem?
However, I have tried install pyinstaller under C:\Python27\Scripts to try to avoid the conflict between 2 pythons. (I am not sure if this could still cause the problem but I just try to list all the details I know for the question.)
New update. 12/16. I have tried to move my target file (to convert) to the script folder, where pyinstaller is installed, the file will be converted successfully. But the script folder will be messed up because multiple folders and files will be generated.
I have added the problem that generated from cmd below :)
