python - TT_Load_Glyph_Header python 崩溃

问题描述

我正在运行一个带有 python/cython 后端的家庭构建的烧瓶 webapp。在 macOS 11.4 上的 webapp 运行时，会发生突然的系统崩溃。我怀疑崩溃是由于使用以下命令将 matplotlib 图形转换为 html

tmpfile = BytesIO()
fig.savefig(tmpfile, format='png', transparent=True, bbox_inches='tight', pad_inches=0.1)
encoded = base64.b64encode(tmpfile.getvalue()).decode('utf8')
html = "<img src='data:image/png;base64,{}'>".format(encoded)

崩溃报告中的重要部分

如果有帮助，这是 webapp 转换为 html 的图形类型。非常忙于希腊字母！ 在此处输入图像描述

我更新了 matplotlib 及其所有依赖项。恐怕这是macos问题......任何建议都会有所帮助。
