Dear community,

I was trying to install pyptv in the anaconda environment with the following command:

python -m pip install --upgrade pip

pip install numpy

pip install pyptv --index-url https://pypi.fury.io/pyptv --extra-index-url https://pypi.org/simple

See attached for the error message I got. How can I fix the error?

Thanks in advance,

Chris

At the moment we have Windows only on Python 3.10 or older 3.7

Create an environment with

conda create -n openptv3 Python=3.10

conda activate openptv3

… and then the installation commands

I just installed pyptv but when I tried to download the test case with the command: git clone --depth 1 -b master --single-branch https://github.com/OpenPTV/test_cavity.git

I got this error message:

Great. So hopefully this is the last bug of enable we need to patch. Please, copy this file over the corrupted one:

cp pathdata.py C:\users\chris\anaconda3\envs\openptv3\lib\site-packages\enable\savage\svg\

pathdata.py

I can open and run the test_cavity now. However, when I close pyptv I got this message:

Thanks for reporting. Don’t know how to solve this. If OpenPTV works - I am happy.
