I have been trying to draw heatmap to .gif file but having issues with shapes. Can someone help me about this issue or anyone has the same error?

The following required packages can not be built:

• freetype, png

from heatmappy import Heatmapper

File "/usr/local/lib/python2.7/dist-packages/heatmappy/heatmap.py", line 102
class GreyHeatMapper(metaclass=ABCMeta):
^
SyntaxError: invalid syntax

I´m trying to create a heatmap on my video.

My video is too large, and my vector of points also big. When I run my program, it gives me a Memory Error. I think the error is because i´m returning a list(heatmap_clips) and it occupies the entire memory.

Can you help solving this problem please?

Thanks

Hi,
do you know why alpha strength doesn't work?

     16 heatmap = heatmapper.heatmap_on_img(patches, img)
     17 ax.imshow(heatmap)

TypeError: __init__() got an unexpected keyword argument 'alpha_strength'

Thanks

1. Just download the zip file.
2. Unzip It
3. Open the requirements.txt with a text editor.
4. Replace the text with:

numpy>=1.17.3
matplotlib>=1.5.0
moviepy==1.0.3
Pillow>=6.2.0
pyparsing>=2.0.6 #
python-dateutil>=2.4.2 #
pytz==2015.7 #
six==1.10.0 #
wheel==0.24.0 #

5. Open a terminal in that folder. (Windows - Shift + Right Click then select Open Powershell | Linux u know how) and run python setup.py install --user.
6. Should be the solution to the problems.
