PyANSYS installation #373

Hi everyone,

I’m Parth Swaroop working in the simulations team in Applied Materials.

I want to install PYANSYS in the system(Windows 10) which has no internet access. If need be, then i can request for access (I will come to that later).

I intend to create a document so that my team members can also follow it. Since there are many different type of Ansys users in group, I would like a one procedure fits all.

I found that there are online and offline options both for installation here :https://github.com/ansys/pyansys

My first attempt was to go for offline method. So what I really did is as below :
1)Install Conda with admin rights and add it system environment variables. This, I was successful in doing. My C:\ProgramData\Anaconda3 has the python 3.11 package, with Jupyter, Spyder environment and so on. I intend to use Spyder to write my codes since I'm comfortable with that interface. My path file has C:\ProgramData\Anaconda3\Script;C:\ProgramData\anaconda3;C:\ProgramData\anaconda3\Lib;

Install PyANSYS package. I have downloaded pyansys-v2023.2.9-all-wheelhouse-Windows-3.11 and extracted package. I used conda prompt to install the package. I started with ansys_api_fluent-0.3.12-py3-none-any.whl. It prompted me or showed the error that I first need to install grpcio-1.56.2-cp311-cp311-win_amd64.whl, which i did. Then it asked for one more package before which i was able to install the above fluent-api.

Do I have to install all .whl one by one or on need basis? Is there a simple way in which I can install entire package in one go?

If having the internet access is the easiest way then do let me know. However, I can access only specific pages which i request for. Can you point me to the list of URL from Ansys for which access is required during installation of PyAnsys? Subsequently can you tell the step to install them?

My knowledge installation using python is beginner/novice level.

Hi @swparth - thanks a lot for opening this discussion! We are glad that you are considering the use of PyAnsys for your workflows.

If you have no internet connection on your machines, then we recommend that you use our wheelhouses (available in the Releases page of this repository). Select your OS and Python version adequately before downloading it.

Next step is to install the wheelhouse. We recommend that you create a dedicated Python environment for this (conda environment or pip virtual env, doesn't matter). In order to install all the packages inside the wheelhouse you can perform as follows:

unzip pyansys-v2023.2.10-all-wheelhouse-Windows-3.11.zip wheelhouse
pip install pyansys -f w…

pip install pyansys -f wheelhouse --no-index --upgrade --ignore-installed

This (line of code 2) should install all the dependencies inside the wheelhouse folder, where we extracted our ZIP file (line of code 1)

If you don't have internet access it might be a bit complicated. I would suggest that you provide access to PyPI in general (because there will be many calls to it).

Some of the PyAnsys dependencies might be entering in conflict with your libraries. One option is that whenever you download the wheelhouse ZIP file, you also delete the wheel related to psutils inside it- if that's the one causing your issues locally.

And yes, looks like the extra dependencies are not being packaged properly. I will have to give it a look at our workflows - for some reason they are not being packaged.

Yep, the -f option installs all the wheels in the wheelhouse.

My understanding is that it will just install the ones specified (here, pyansys) and its dependencies. Which means to get pyansys-parametric etc. the command should be

pip install pyansys[all] -f {your_unzipped_folder_name} --no-index --upgrade --ignore-installed

Note the added [all].

But, this still leaves the problem that these packages are not actually present in the wheelhouse.

Yes - thanks @greschd for reporting the issue. I just opened the PR to fix this ansys/actions#343

But you are totally right, by default it won't install parametric or visualization. You need to add the all target.

I will be able to know this apriori or only in retrospect? It could be different for different systems?

Also can you tell me which version 'pip uninstall psutil' will uninstall? psutil (5.9.0 or 5.9.5) ? I should be having at-least one right?

RobPasMue Sep 29, 2023

You should uninstall 5.9.5 from what I can see in your logs and have 5.9.0 installed.

And it seems to me that you will only be able to know this in retrospective.

pip install pyansys[all] -f {your_unzipped_folder_name} --no-index --upgrade --ignore-installed

this is what i get when I try to run the above command :

ERROR: Cannot install pyansys[all]==2023.2.10 and pyansys[all]==2023.2.9 because these package versions have conflicting dependencies.

The conflict is caused by:
pyansys[all] 2023.2.10 depends on ansys-meshing-prime==0.4.1
pyansys[all] 2023.2.9 depends on ansys-mapdl-reader==0.52.13; extra == "all"

To fix this you could try to:

loosen the range of package versions you've specified
remove package versions to allow pip attempt to solve the dependency conflict

Yes, that's because you are installing different versions of the PyAnsys metapackage - and they are not compatible. If you want to install a new version of the PyAnsys metapackage (i.e. 2023.2.10) you have to start from scratch =)

swparth Sep 29, 2023

Does starting from scratch mean uninstalling PyANSYS and reinstalling? That's what i actually did.
I ran the following :

 C:\ProgramData\anaconda3>pip uninstall pyansys
Found existing installation: pyansys 2023.2.9
Uninstalling pyansys-2023.2.9:
  Would remove:
    c:\programdata\anaconda3\lib\site-packages\pyansys-2023.2.9.dist-info\*
    c:\programdata\anaconda3\lib\site-packages\pyansys\*
Proceed (Y/n)? y
  Successfully uninstalled pyansys-2023.2.9

(base) C:\ProgramData\anaconda3>pip install pyansys[all] -f pyansys-v2023.2.9-all-wheelhouse-Windows-3.11 --no-index --upgrade --ignore-installed

RobPasMue Sep 29, 2023

Yes but you only uninstalled PyAnsys and not all its dependencies. If you want to remove all the dependencies of a package, the only way I know is using the pip-autoremove package

pip install pip-autoremove
pip-autoremove pyansys -y

However, the fastest and cleanest way to do it would be to delete the existing virtual environment and create a new one

I think because of no internet, i'm unable to create a virtual environment:

conda create --name pyansysenv 
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/current_repodata.json>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

If your current network has https://repo.anaconda.com blocked, please file
a support request with your network engineering team.

'https//repo.anaconda.com/pkgs/main/win-64'

Should i halt my installation process till this bug (ansys/actions#343) is resolved?

Also , i reinstalled conda (since i did not create virtual environment previously and auto-remove was not successful) tried pip install for pyansys (All)

HI @swparth - answering both #373 (reply in thread) and #373 (comment)

If you do not have an internet connection, running pyansys[all] with the existing wheelhouse ZIP file won't work, because it does not contain all the needed wheels. That is why you are getting this error:

ERROR: No matching distribution found for ansys-mapdl-reader==0.52.13; extra == "all"

I would suggest that you wait until we fix this issue - we would need to perform a new release of the PyAnsys metapackage. Please hold - I will inform you once it is ready.

Hi @swparth - new release is out with the bugfix for the wheelhouse. These wheelhouse now contain all dependencies.

Hi,

I tried a different work-around for this since, i was unable to create a virtual environment in a offline system.
Both online/offline are windows system.

New strategy :

Install conda and py3.11.4 in laptop (with internet access) ,
Create a virtual environment of the base conda packages. (conda create --name py_blade --clone base)
Installation pyansys[all] inside the virtual environment. (pip install pyansys[all]==2023.2.11)
Pack the conda file into a .tar.gz . (conda pack -n py_blade_pack)
Unpack this in the offline system.

However I see a problem with three packages during PYANSYS installation :

  Attempting uninstall: psutil
    Found existing installation: psutil 5.9.0
    Uninstalling psutil-5.9.0:
      Successfully uninstalled psutil-5.9.0
  Attempting uninstall: h5py
    Found existing installation: h5py 3.7.0
    Uninstalling h5py-3.7.0:
      Successfully uninstalled h5py-3.7.0
  Attempting uninstall: click
    Found existing installation: click 8.0.4
    Uninstalling click-8.0.4:
      Successfully uninstalled click-8.0.4

And then i pack my environment into conda pack :

Files managed by conda were found to have been deleted/overwritten in the
following packages:
- click 8.0.4:
    lib\site-packages\click-8.0.4.dist-info\direct_url.json
    lib\site-packages\click-8.0.4.dist-info\installer
    lib\site-packages\click-8.0.4.dist-info\license.rst
    + 7 others
- h5py 3.7.0:
    lib\site-packages\h5py-3.7.0.dist-info\direct_url.json
    lib\site-packages\h5py-3.7.0.dist-info\installer
    lib\site-packages\h5py-3.7.0.dist-info\license
    + 5 others
- psutil 5.9.0:
    lib\site-packages\psutil-5.9.0.dist-info\direct_url.json
    lib\site-packages\psutil-5.9.0.dist-info\installer
    lib\site-packages\psutil-5.9.0.dist-info\license
    + 6 others

Hi @RobPasMue and @greschd. Thank you so much for the all the support. I really appreciate all the prompt response.
The above strategy worked for me. PyANSYS has been depolyed in the offline system.
I want to close this discussion.

Hi,
I'm not really sure,
but ansys-mapdl-reader 0.53.0 seems to be unable to be installed in python3.8.

Hi @whplace - in case you want to use ansys-mapdl-reader on Python 3.8, you need to build the package from scratch. Support for Python 3.8 was dropped in most of our PyAnsys libraries starting on October and following NEP-0029
