I'm having some problems with my flask application which I never had before until today and I haven't changed anything so it's quite confusing
So it my app.py
#app.route('/view.html')
def data():
try:
path = 'app/database.db'
con = sqlite3.connect(path)
cur = con.cursor()
con.row_factory = sqlite3.Row
rows = cur.execute("select * from table").fetchall()
return render_template('layouts/default.html',
content=render_template('pages/view.html',
rows=rows))
except sqlite3.OperationalError:
return render_template('layouts/default.html',
content=render_template('pages/view.html'))
The idea is that if there is no table in the database yet, it will catch the error and just return the view.html with no data but for some reason it does not work anymore
Just realised I completely forgot to add the error, my bad

Hi I have encountered such problem when loading the function install_tensorflow() in r.
I don't know what to do with this error. Any help will be greatly appreciated!
Below is the error message

I got two solution for this from here, one is to remove the pid file /var/run/nginx-nr-agent/nginx-nr-agent.pid and than start/restart it. And second solution is to restart the server.

Hi I am using biopython to pull files from NCBI using Entrez. The program works on small files but on larger files I get an error. I would really appreciate some insight or help figuring out what went wrong.
Here is the program:
from Bio import Entrez
Entrez.email = "jbro262#lsu.edu"
search_handle = Entrez.esearch(db="nucleotide",term="Saimiri",usehistory="n")
search_results = Entrez.read(search_handle)
search_handle.close()
gi_list = search_results["IdList"]
count = int(search_results["Count"])
a = open("Numfile.txt", "a+")
a.write("The number of Saimiri files are :")
a.write(str(count))
a.write("\n")
a.close()
webenv = search_results["WebEnv"]
query_key = search_results["QueryKey"]
batch_size = 25
out_handle = open("SaimiriDNA.fasta", "w")
for start in range(0,count,batch_size):
end = min(count, start+batch_size)
print("Going to download record %i to %i" % (start+1, end))
fetch_handle = Entrez.efetch(db="nucleotide", rettype="fasta", retmode="text", retstart=start, retmax=batch_size, webenv=webenv, query_key=query_key)
data=fetch_handle.read()
fetch_handle.close()
out_handle.write(data)
out_handle.close()
Here are the errors:

Does this mean something is going wrong with my server while the files are downloading?
