CalledProcessError:在jupyter笔记本中返回非零退出状态1

Question

df = read_pdf("MDCAT_2020_Result.pdf", encoding='utf-8', stream=True,java_options=["-Xmx256m"], pages='all')

我想将MDCAT_2020_Result.pdf转换为CSV文件，然后转换为数据帧，但出现以下错误：

CalledProcessError: Command '['java', '-Xmx256m', '-Dfile.encoding=UTF8', '-jar', '/opt/conda/lib/python3.8/site-packages/tabula/tabula-1.0.4-jar-with-dependencies.jar', '--pages', 'all', '--stream', '--guess', '--format', 'JSON', 'MDCAT_2020_Result.pdf']' returned non-zero exit status 1.
