The output.fa is null

[myshu2017-03-14]

Hi,
I installed the nanocall on Ubuntu 16.04. The command I used just as below:

nanocall /nanopore-datas/20170907_1414_FAH10633-RS-20170907/fast5/pass/0/DESKTOP_QKGLFDD_20170907_FAH10633_MN20782_sequencing_run_FAH10633_RS_20170907_53523_read_1023_ch_3_strand.fast5 >output.fa 2>log

And the results of nanocall basecalling(output.fa) using our sequencing fast5 file (I choosed the local basecalling in the MinKNOW, the test fast5 file directory is /nanopore-datas/20170907_1414_FAH10633-RS-20170907/fast5/pass/0/) is null.
The log file just as below:

There are no error when running...
So what the wrong here? Can you help me?

Looking for your reply. Thank you very much!
